Abstract

Dichloroindium hydride (Cl₂InH) generated in situ from the combination of a catalytic amount of indium(III) chloride and sodium borohydride in acetonitrile reduces activated vic-dibromides to the corresponding (E)-alkenes in excellent yieids.

Key words

reductions - (E)-alkenes - vic-dibromides - indium(III) chloride - sodium borohydride
