Computed Properties of C18H34BF4P. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Tricyclohexylphosphonium tetrafluoroborate, is researched, Molecular C18H34BF4P, CAS is 58656-04-5, about Employing Pd-Catalyzed C-H Arylation in Multicomponent-Multicatalyst Reactions (MC)2R: One-Pot Synthesis of Dihydrobenzoquinolines.
Alkenylchloropyridines such as I (R = F3C, MeSO2, NC, Me, 4-F3CC6H4, H) underwent one- and two-pot tandem hydroarylation reactions with arylboronic acids such as 3-thienylboronic acid and 4-R2C6H4B(OH)2 (R2 = Me2N, PhO, MeO, Me, t-Bu) in the presence of [Rh(ethene)2Cl]2 and either 1,2-bis(diphenylphosphino)benzene or a nonracemic bicyclooctadienecarboxamide followed by palladium-catalyzed cyclization in the presence of Pd(OAc)2, tricyclohexylphosphonium tetrafluoroborate, and K2CO3 to give fused dihydroquinolines such as thienoquinolines II (R = F3C, MeSO2, NC, Me, 4-F3CC6H4) and dihydrobenzoquinolines such as III (R2 = Me2N, PhO, MeO, Me, t-Bu). In the presence of a nonracemic bicyclooctadienecarboxamide, rhodium-catalyzed hydroarylation followed by palladium-catalyzed cyclization reactions of I (R = F3C; R1 = n-Pr) with 4-phenoxyphenyl and 4-tert-butylphenyl boronic acids yielded III (R1 = n-Pr; R2 = PhO, t-Bu) in 91:9 and 93:7 er, resp. Tandem hydroarylation, cyclization, and dehydrogenation of I (R = MeSO2) with 3-thienylboronic acid yielded a methanesulfonylbenzoquinoline in 95% yield.
After consulting a lot of data, we found that this compound(58656-04-5)Computed Properties of C18H34BF4P can be used in many types of reactions. And in most cases, this compound has more advantages.
