Metal-catalyzed C–H borylation reactions are transition metal catalyzed organic reactions that produce an organoboron compound through functionalization of aliphatic and aromatic C–H bonds and are therefore useful reactions for carbon–hydrogen bond activation.
 Metal-catalyzed C–H borylation reactions utilize transition metals to directly convert a C–H bond into a C–B bond.
 This route can be advantageous compared to traditional borylation reactions by making use of cheap and abundant hydrocarbon starting material, limiting prefunctionalized organic compounds, reducing toxic byproducts, and streamlining the synthesis of biologically important molecules.
 Boronic acids, and boronic esters are common boryl groups incorporated into organic molecules through borylation reactions.
 Boronic acids are trivalent boron-containing organic compounds that possess one alkyl substituent and two hydroxyl groups.
 Similarly, boronic esters possess one alkyl substituent and two ester groups.
 Boronic acids and esters are classified depending on the type of carbon group (R) directly bonded to boron, for example alkyl-, alkenyl-, alkynyl-, and aryl-boronic esters.
 The most common type of starting materials that incorporate boronic esters into organic compounds for transition metal catalyzed borylation reactions have the general formula (RO)B-B(OR).
 For example, Bis(pinacolato)diboron (BPin), and bis(catecholato)diborane (BCat) are common boron sources of this general formula.
Lucky Lehrer is a drummer from Los Angeles, California who was voted the best punk drummer of all-time by fanzine, "Flipside".
 He was originally trained in jazz then played in influential LA punk rock bands, particularly the Circle Jerks, Redd Kross, Bad Religion, Darby Crash Band and LA's Wasted Youth, among others.
 Lehrer also appeared in three notable documentary films charting the punk rock music scene.
 He is the brother of LA's Wasted Youth guitarist Chett Lehrer.
 Lehrer also teaches drums, with notable students being future Bad Religion drummers Pete Finestone and Bobby Schayer.
 He was an early developer of hardcore punk drumming and he has been called the "Godfather of hardcore drumming".
Germicide is a live album by the punk rock band the Germs.
 Performing live at the Whisky a Go Go in 1977, Darby Crash and the Germs were at the beginning of their career.
 At this time, Crash performed using the name Bobby Pyn.
 Darby and the audience feud constantly throughout the show.
 Disc jockey Rodney Bingenheimer appears at the beginning as master of ceremonies, and "Belinda" briefly takes the mic to introduce the band, who she describes as "sluts".
(GI) is the only studio album by American punk rock band the Germs.
 Often cited as one of the first hardcore punk albums, it was released in the United States in October 1979 on Slash Records with catalog number SR 103.
 The album was later released in Italy in 1982 by Expanded Music with the catalog EX 11.
 The album's title is an acronym for "Germs Incognito", an alternate name the band used to obtain bookings when their early reputation kept them out of Los Angeles-area clubs.
 After "(GI)"<nowiki>'</nowiki>s release, the band would only undertake one more recording session, for the soundtrack album to the Al Pacino's 1980 film "Cruising".
 A year after the release of "(GI)", on December 7, 1980, vocalist Darby Crash committed suicide.
Andi Kravljaca is a Bosnian-born Swedish heavy metal singer.
 His main band is the progressive metal band Aeon Zen, although he is perhaps best known as vocalist for Swedish progressive metal band, Seventh Wonder, appearing on the band's first album, Become, in 2005.
 He was born in Sarajevo.
What We Do Is Secret is a 2007 American biographical film about Darby Crash, singer of the late-1970s Los Angeles punk rock band the Germs.
 Rodger Grossman directed the film and wrote the screenplay, based on a story he had written with Michelle Baer Ghaffari, a friend of Crash's and co-producer of the film.
 Shane West stars as Crash, while Rick Gonzalez, Bijou Phillips, and Noah Segan respectively portray Germs members Pat Smear, Lorna Doom, and Don Bolles.
The Darby Crash Band was a music project started by Darby Crash and Pat Smear, founding members of Los Angeles punk rock band the Germs, formed after the Germs split in 1980.
 They recruited bassist David "Bosco" Danford and Circle Jerks drummer Lucky Lehrer and began playing shows in Los Angeles.
 The band's setlists would include a number of well-known songs from the Germs' archives, as well as newly written material.
 The band never recorded and played only a small number of shows before Darby's death on the 7th of December, 1980.
Darby Crash (formerly Bobby Pyn; born Jan Paul Beahm; September 26, 1958 – December 7, 1980) was an American punk rock vocalist and songwriter who, along with long-time friend Pat Smear (born Georg Ruthenberg), co-founded the punk rock band the Germs.
 He committed suicide by way of an intentional heroin overdose.
 In the years since his suicide at the age of 22, the Germs have attained legendary status among punk rock fans and musicians alike, as well as from the wider alternative rock and underground music community in general.
 Crash has come to be revered as a unique and talented songwriter; his myriad literary, musical and philosophical influences, which varied from Friedrich Nietzsche and David Bowie to Charles Manson and Adolf Hitler, resulted in lyrics that were unusually wordy and impressionistic in the realm of punk rock at the time, immediately setting Crash and his band apart from most other Los Angeles punk groups that sprang up in the late 1970s.
The Germs were an American punk rock band from Los Angeles, California, United States, originally active from 1977 to 1980.
 The band's main early lineup consisted of singer Darby Crash, guitarist Pat Smear, bassist Lorna Doom and drummer Don Bolles.
 They released only one album, 1979's "(GI)", produced by Joan Jett, and were featured the following year in Penelope Spheeris' documentary film "The Decline of Western Civilization", which chronicled the Los Angeles punk movement.
Shane West (born Shannon Bruce Snaith; June 10, 1978) is an American actor, punk rock musician, and songwriter.
 West is known for his portrayal of Eli Sammler in the ABC family drama "Once and Again", Landon Carter in "A Walk to Remember", Darby Crash in "What We Do Is Secret", Dr. Ray Barnett in the NBC medical drama "ER" and Michael Bishop in The CW spy drama "Nikita".
 He also starred in the WGN fantasy/adventure/historical drama "Salem" as John Alden.
