Remarkably selective reduction of the alpha,beta-carbon-carbon double bond in highly activated alpha,beta,gamma,delta-unsaturated alkenes by the InCl3-NaBH4 reagent system.
A combination of sodium borohydride and a catalytic amount of indium(III) chloride in acetonitrile reduces exclusively the alpha,beta-carbon-carbon double bond in alpha,beta,gamma,delta-unsaturated diaryl ketones, dicarboxylic ester, cyanoester, and dicyano compounds.
