Question: What type of group does D. R. Horton and Kimberly-Clark have in common?
Context: A coupling reaction in organic chemistry is a general term for a variety of reactions where two hydrocarbon fragments are coupled with the aid of a metal catalyst.  In one important reaction type a main group organometallic compound of the type RM (R = organic fragment, M = main group centre) reacts with an organic halide of the type R'X with formation of a new carbon-carbon bond in the product R-R' "Playboy" is a song composed by Brian Holland, Robert Bateman, Mickey Stevenson and singer Gladys Horton, lead vocalist of the Motown singing group The Marvelettes, who recorded the song and released it as a single on Motown's Tamla imprint in 1962.  The single, led by Horton, is about a man who fools around with a lot of women and the woman who narrates the story warns him to stay away from her due to the stories she heard of him "running around with every woman in town".  Horton is helped out in the song by her Marvelettes cohorts Wanda Young, Georgeanna Tillman, Katherine Anderson & Juanita Cowart.  This was released as the third single by the Marvelettes and was their second top ten pop hit reaching number seven on the charts while reaching number four on the R&B chart. "Twistin' Postman" is a song recorded by Motown singing group The Marvelettes, who released it in 1961, and was the follow-up to their smash debut single, "Please Mr. Postman".  Much like that song, it is led by original Marvelette Gladys Horton, and is partially based on the then-current Twist dance move.  The song's subject is a sequel of the original "Postman" single and this time the narrator is finally happy that the postman has delivered a letter from the narrator's boyfriend.  The song became a modest hit for the group reaching number thirteen on the R&B charts and number thirty-four on the pop singles chart in early 1962.  A third single, "Playboy", would return the group to the top ten of the pop and R&B charts later that year. 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. "Crazy" is a song written and produced by the Americans songwriters and music producers John V. Anderson, Steve Williams and Steve Horton.  The song was recorded by popular American R&B vocal group the Manhattans and released in 1983 on the album "Forever By Your Side" by Columbia Records.  "Crazy" was released as a single the same year, reaching No. 4 on the R&B chart and No. 72 on the "Billboard" Hot 100.  Besides the United States, "Crazy" was also released as a single in the United Kingdom, where it peaked at No. 63. D. R. Horton is the largest home construction company in the United States based on its 37,380 houses sold (up 26% year over year) and closed 36,648 (up 28% year over year) in fiscal year 2015.  D.R. Horton posted revenues of $10.7 billion in 2015.  D. R. Horton was founded in 1978 by Donald R. Horton in the Dallas–Fort Worth metroplex.  The company's headquarters moved from Downtown Fort Worth to a newly constructed 200,000 square foot, four-story building in Arlington, Texas in 2017.  D. R. Horton operates three separately branded divisions: Emerald Homes, Express Homes, and Freedom Homes.  Express Homes is tailored to entry-level buyers while the Emerald Homes brand is sold as luxury real estate.  In July 2016, D.R. Horton announced the launch of their Freedom Homes division.  The communities will be built as active adult housing and are set to be debuted in Florida, Illinois,Texas and Arizona. A thiosulfoxide is a chemical compound containing a sulfur to sulfur double bond of the type RR'S=S with R and R' both alkyl or aryl residues.  The thiosulfoxide has a molecular shape known as trigonal pyramidal.  Its coordination is also trigonal pyramidal.  The point group of the thiosulfoxide is C.  A 1982 review concluded that there was as yet no definitive evidence for the existence of stable thiosulfoxides which can be attributed to the double bond rule which states that elements of period 3 and beyond do not form multiple bonds.  The related sulfoxides of the type RR'S=O are very common.  Many compounds containing a sulfur-sulfur double bond have been reported in the past although only a few verified classes of actually stable compounds exist, closely related to thiosulfoxides. Kimberly-Clark Corporation is an American multinational personal care corporation that produces mostly paper-based consumer products.  Kimberly-Clark brand name products include Kleenex facial tissue, Kotex feminine hygiene products, Cottonelle, Scott and Andrex toilet paper, Wypall utility wipes, KimWipes scientific cleaning wipes, and Huggies disposable diapers. "I'll Keep Holding On" is a song composed by Mickey Stevenson and Ivy Jo Hunter and recorded by Motown singing group The Marvelettes, who released the single on the Tamla imprint in 1965.  Peaking at #34 on the Billboard Hot 100 (and #11 on the R&B charts), the single returned the group to the top forty after a year recording songs that performed below the top forty.  This was among the first A-side singles that longtime Marvelettes member Wanda Young sung lead on.  Before 1965, the majority of the leads in Marvelettes songs had belonged to original member Gladys Horton.  The single features a woman determined to win the love of an unknowingly conquest telling him that she'll convince him to love her "until my will to resist is gone".  Her Marvelettes band mates Gladys Horton and Katherine Anderson egg her on with her ad-libbing "oh yeah/sho' nuff" in the bridge leading up to the chorus.  The single was covered by British mod-pop act, The Action in 1966, released as "I'll Keep On Holding On".  It then returned across the Atlantic in 1998 to be released on Mink Rat or Rabbit by the Detroit Cobras. Langeronyx is an extinct genus of basal rhynchosaurid known from the early Middle Triassic (Anisian stage) Bromsgrove Sandstone Formation of Warwickshire, UK.  It contains a single species, Langeronyx brodiei, originally included in the genus "Rhynchosaurus".  "R. brodiei" was first described and named by Michael Benton in 1990, but its redescription by Martín D. Ezcurra, Felipe Montefeltro and Richard J. Butler in 2016 recovered it as more closely related to the more advance hyperodapedontine than to the type species of "Rhynchosaurus" and thus it was moved to its own genus.  The generic name "Langeronyx" honors the Brazilian paleontologist Max Cardoso Langer in recognition of his rhynchosaur research, combined with the Greek "onyx" ("óνυξ") meaning "claw", a common suffix for rhynchosaur genera.  "L. brodiei" is known solely from the holotype, a partial skull divided into the two specimens WARMS G6097/1 and NHMUK PV R8495, housed in the Warwickshire Museum, Warwick and Natural History Museum, London, respectively.  Other specimens originally referred to "R. brodiei" either do not overlap with its type or can be just as likely referred to other basal rhynchosaurids (like "Fodonyx spenceri" and "Bentonyx sidensis" from the coeval Otter Sandstone Formation, UK).  "L. brodiei" is one of two basal archosauromorphs known from the Bromsgrove Sandstone Formation, the other being the lesser known "Rhombopholis scutulata".
