Various types of aryl, benzyl, vinyl, phenacyl, and allyl halides were subjected to reaction with N-benzyl-1, 4dihydronicotinamide (BNAH), in the presence of a catalytic amount of chlorotris (triphenylphmphine) rhodium (I) or palladium (I1) acetate. The carbon-halogen bonds in these compounds were selectively reduced to the carbon-hydrogen bonds in moderate to excellent yield. This new kind of reduction system has synthetic advantages ...
