p-TolSbH₂ reacts with styrene with formation of ethylbenzene and (p-TolSb)_n (n=4, 5 in benzene). The action of phenyl acetylene on p-TolSbH₂ gives styrene. Addition of Ph₂SbH on phenyl acetylene in the presence of AIBN (azodiisobutyronitrile) yields 95% trans- and 5% cis-PhCH=CHSbPh₂. Ph₂SbH reacts with benzaldehyde in the presence of AIBN with formation of benzylalcohol (98%) and with various prochiral ketones in the presence of chiral auxiliares to give alcohols in high optical yields. Benzotrichloride reacts with Ph₂SbH in the presence of PdCl₂ to give benzylidene chloride. 1-Bromo adamantane, dibromo cholestanol, 2-chloro acetophenone, cinnamic acid chloride, and chloro acetophenone react with Ph₂SbH/AIBN with substitution of the halogen atoms by hydrogen. Benzylbenzoate is formed the by action of Ph₂SbH/AIBN on benzoyl chloride.
