Pentacarbonylhydridomanganese is an organometallic compound with formula HMn(CO)5. This compound is one of the most stable "first-row" transition metal hydrides.

Preparation
It was first reported in 1931. Of the several ways to produce this compound, is the protonation of the pentacarbonyl manganate anion.  The latter is formed from reduction of dimanganese decacarbonyl, (Mn(CO)5)2. The reaction is shown below.

LiHB(C2H5)3 (Superhydride) + ½ Mn2(CO)10 → Li[Mn(CO)5] + ½ H2 + (C2H5)3B

Li[Mn(CO)5] + CF3SO3H → HMn(CO)5 + 

Salts of  can be isolated as crystalline  (μ-nitrido—bis-(triphenylphosphorus)) salt, which is smoothly protonated by CF3SO3H.

PPN[Mn(CO)5] + CF3SO3H → HMn(CO)5 + 

This compound can also be formed by the reaction of a solution of pentacarbonyl(trimethylsilyl)manganese with water.  The reaction is shown below.

2 (CO)5MnSiMe3 + H2O → HMn(CO)5 + Me3SiOSiMe3

Structure and properties

The compound has octahedral symmetry  and its molecular point group is C4v. The H-Mn bond length is 1.44 ± 0.03 Å. A gas phase electron diffraction study  confirms this data.

The structure of HMn(CO)5 has been studied by many methods including X-ray diffraction, neutron diffraction, and electron diffraction. HMn(CO)5 can be  related to the structure of a hexacarbonyl complex such as , and therefore has the following similar properties. The occupied molecular orbitals on the top are the 2 t2g orbitals. They are characterized as metal 3dπ orbitals. Since the antibonding 2π orbitals interact with the carbonyl groups, (or in this case, ) the t2g orbital is stabilized compared to the 3dπ orbital, which in turn will cause changes in the sigma and pi interactions.

Main reactions

The pKa of HMn(CO)5 in water is 7.1. It is thus comparable to hydrogen sulfide, a common inorganic acid, in its acidity.

A common reaction involving the HMn(CO)5 species is substitution of the CO ligands by organophosphines, as occurs both thermally and photochemically.  In this way the following derivatives form: MnH(CO)3[P]2, MnH(CO)2[P]3, and MnH(CO)[P]4, (where [P] = P(OEt)3, PPh(OEt)2, PPh2OEt, PPh(OiPr)2).

The compound HMn(CO)5 can be used to reduce olefins and other organic compounds, as well as metal halides.

This compound can be methylated with diazomethane.

HMn(CO)5 + CH2N2 → Mn(CO)5CH3 + N2

The Galician Campaign of 1384 was a Portuguese naval campaign commanded by a Castillian noble, Don Pedro de Trastámara, who sided with John I of Portugal. The Portuguese, whose main ship was the Royal galley itself, made a series of attacks on Galicia, conquering the towns of Baiona, A Coruña and Neda and burning the coastal town of Ferrol to the ground. Additionally, the Portuguese destroyed approximately 2 large Castilian ships and captured a galley. All three ships were carrying supplies to the Castilian army besieging Lisbon.

When the Portuguese returned to Porto celebrations were held to honour their victory.

The Hamilton-Skotch Corporation was a manufacturing company originally headquartered in Hamilton, Ohio, United States. The company popularized the Skotch Kooler brand of plaid decorated coolers in the 1950s.

History 
Hamilton-Skotch was founded as the Hamilton Metal Products Company in 1919 in Hamilton, Ohio. It was formed by Louis Piker, J. Schlichter and Phillip Piker when they raised $30,000 in capital and merged their businesses, the Hamilton Sheet Metal Company and the Schlichter Manufacturing Company. Hamilton Sheet Metal produced mailboxes and other sheet metal-based goods, while Schlichter Manufacturing was primary known for their Climax brand food graters. After the merger, use of the Climax brand name expanded to their sheet metal products, like tackle boxes and filing boxes. By the 1950s they were also selling metal signage and plaques.

Skotch Koolers

Their most famous product was the Skotch Kooler. The design originated from a minnow bucket, a bucket used by fishermen to store living fish they had caught. The company was in debt, needed to expand its product line, and a minnow bucket seemed like a sensible choice, as they were already an established maker of tackle boxes. The product failed to sell well, due to existing competition, so the bucket was used as a basis for a cooler instead. While the product was an excellent cooler, its unique bucket shape was unfamiliar to consumers used to seeing rectangular coolers, and the original styling was nothing special. In 1951 the company hired Petra Cabot to restyle the cooler. The new design featured a distinctive red, black, and yellow plaid decoration, leather accents, and Cobat's signature around the edge. Its fashionable design and solid cooling ability made it desirable, but its original price of $49.95 ($455 adjusted for inflation to 2016 dollars) limited sales. The design was simplified soon after and it was repriced at $7.95. At that price, sales more than doubled. It became so recognizable that the company eventually rebranded itself the Hamilton-Skotch Corporation and began using the Skotch name on many of its other products.

Fate

The Hamilton-Skotch Corporation failed to weather the industrial transition that swept the United States in the mid-20th century. By 1970 it had closed its Hamilton plant and moved what remained of its production to its existing facility in Ottawa, Kansas. By the late 70s its trademarks had lapsed and all of its products had disappeared from the market.

In 2017, with the goal of resurrecting the iconic midcentury brand, the Skotch trademarks were purchased by a trio from Minneapolis, Minnesota. The company was renamed to Skotch Kooler USA and the products have been redesigned for a modern lifestyle while retaining their original charm and artisanal construction. With plans to expand the line further in the future, the brand relaunched in 2020 with new-and-improved versions of the Skotch Soft Kooler and Skotch Grill.

Pamela's Diner is a prominent chain of diners in Pittsburgh, Pennsylvania, USA. Its specialties are crêpe-style pancakes, omelets and Lyonnaise potatoes. It is "treasured" and is considered to be in the "pantheon of pancake purveyors". In 2013, Pamela's Diner was featured by the Wall Street Journal in a "What to Do in Pittsburgh" feature story.

Pamela's Diner is owned by Gail Klingensmith and Pam Cohen. Both educated as teachers, the business partners handle different tasks, Klingensmith with the more business end and Cohen as "the culinary artist". The first Pamela's Diner location, in the Squirrel Hill neighborhood, opened in 1979. Subsequent locations have opened in Shadyside, the Strip District, Millvale, Oakland and Mt. Lebanon.

During the 2008 United States presidential election, Barack Obama visited Pamela's Diner for a campaign visit. Once elected, President Obama invited Klingensmith and Cohen to the White House for a Memorial Day breakfast with the Obama family and 80 veterans. Later that year, during the 2009 G-20 Pittsburgh summit, President Obama expressed dismay that he was unable to return to Pamela's Diner during that trip, but First Lady Michelle Obama did visit. Incidentally, the Oakland storefront received damage during the protests that accompanied the G-20 summit. 

Pamela's Diner announced in December 2021 that their Squirrel Hill neighborhood location will be closing largely due to COVID-19. With the loss of several long-time employees, the location decided to shut its doors. Opened on Forbes Avenues, before relocating to the Murray Avenue in 2011, it operated in Squirrel Hill around 42 years. The other diner locations will stay open, however. The owners hinted that they are open to another, smaller Squirrel Hill location in the future.

Lamellarins are a group of pyrrole alkaloids first isolated in 1985 from the marine mollusk Lamellaria in the waters of Palau. Over 70 lamellarins and similar compounds were subsequently isolated. Other similar compounds include ningalins, lukianols, polycitones, and storniamides.

Biological activity
These compounds have shown a wide variety of biological activity, including reversal of multidrug resistance, HIV-1 integrase inhibition, and antibiotic activity. Lamellarin D, for example, displays strong cytotoxic activity against tumor cell lines, and is a potent topoisomerase I inhibitor.

Structure
The lamellarins all contain a central pyrrole ring, substituted at the 3 and 4 positions by polyhydroxy- or methoxyphenyls. They are divided into two groups, depending on whether the pyrrole ring is fused or unfused.

Synthesis
The lamellarins have been synthesized by a number of groups, including Isibashi, Steglich, Ruchirawat, Banwell, Alvarez, Gupton, Boger, and Handy.

Steglich synthesis of lamellarin G trimethyl ether
The Steglich synthesis features an oxidative coupling of two benzylic carbons, as well as a Paal-Knorr pyrrole synthesis.

Banwell synthesis of lamellarin K
The Banwell group’s synthesis of lamellarin K includes an intramolecular azomethine ylide cyclization.
