Alexander, Cameron published the artcileSynthesis of a series of ethynyl-substituted triphenylmethanes, Formula: C10H16O2, the publication is Synthesis (1992), 735-7, database is CAplus.
Triphenylmethyl-substituted alkynyl monomers I (R = H, Me) and II, required as part of a study concerning conjugated polyradicals, were prepared in multistep processes. Thus, II was prepared from Ph3CH in 3 steps involving Friedel-Crafts monoacetylation with AcCl, followed by Vilsmeier formylation to give β-chloro aldehyde III, and elimination by KOH in aqueous MeOH/THF.
Synthesis published new progress about 27943-46-0. 27943-46-0 belongs to tetrahydropyran, auxiliary class Tetrahydropyran,Alkynyl,Ether, name is 2-((2-Methylbut-3-yn-2-yl)oxy)tetrahydro-2H-pyran, and the molecular formula is C10H16O2, Formula: C10H16O2.
