Triarylstibines react with α,β-unsaturated aldehydes and ketones in acetic acid at 25°C in the presence of silveracetate and a catalytic amount of palladium(II) acetate to afford the hydroarylation products by conjugate addition in good yields.

Triarylstibines react with α,β-unsaturated ketones and aldehydes in acetic acid at room temperature in the presence of AgOAc and a catalytic amount of Pd(OAc)2 to afford the conjugate addition products (the formal hydroarylated compounds to an olefinic part) in good yields. In contrast, diarylantimony chlorides, arylantimony dichlorides, and diphenylantimony acetate react with the enones and enals
