Palladium Catalyzed Selective 1,4‐Dihydrosilylation of Alkynones

An efficient and selective Pd‐catalyzed 1,4‐dihydrosilylation of alkynones has been firstly described to provide a convenient access to β‐aryl carbonyl compounds under mild conditions. Various β‐aryl carbonyl compounds have been synthesized with good yields and functional group tolerance. β‐aryl carbonyl products have been shown to be further application in the synthesis of secondary alcohol, silyl‐ether, trifluoromethylsilyl‐ether and vinyl acetate derivative.
