Abstract

The addition of aryl-or alkenyl-trimethylstannanes to α, β-unsaturated carbonyl compounds in the presence of a catalytic amount of a cationic rhodium complex ([Rh (cod)(MeCN) 2] BF4) and water to afford the conjugate addition products in good yields was examined. It was observed that addition of water was necessary for the reaction to proceed smoothly. The aryl-or alkenyl-rhodium complex, which is generated by the transmetalation from the ...
