Abstract

Reaction of triarylbismuth difluorides 1 with allyltrimethylsilane 2 in CH2Cl2 in the presence of BF3· OEt2 at low temperature generates allyltriarylbismuthonium compound 3 as a pale yellow solution, in which aromatic hydrocarbons and ethers, triphenylphosphine, dimethyl sulfide, p-toluenesulfinate, and thiophenol are all readily allylated to afford the corresponding allyl derivatives in moderate to good yields.
