“Ene-type” addition of alkenes to phenyl vinylsulfoxide
摘要:
Phenyl vinylsulfoxide reacts under acylating conditions (TFA, TFAA) with isobutene to give double 'ene" alpha,beta-adduct Propene and other alkenes examined afford a beta-"ene" alkylation accompanied by trifluoroacetoxylation at the same carbon atom.
