摘要

Phenyl vinyl sulfones and sulfoxides react with Pd (OAc) 2 to form styryl sulfoxides and sulfones according to the first Mizoroki-Heck reaction reported for these thio derivatives. Only sulfones are able to react by using catalytic amounts of Pd (up to 1 mol%) in the presence of Ag2CO3. 1, 2-Diphenylsulfonyl ethenes, alkynylphenyl sulfones, and other sulfones, less prone to act as acceptors in the Heck-type reactions, can transfer the aryl ...
