Abstract

α,β-Enones undergo an efficient Hosomi-Sakurai reaction with allyltrimethylsilane, in which a catalytic amount of indium is used in the presence of trimethylsilyl chloride as an activator under mild conditions to produce the conjugate addition products in good yields.

Key words

addition reactions - catalysis - indium - Michael additions - silicon
