Abstract

Abstract The regioslective reduction of electron-rich dienes to monoolefins and the reductive cleavage of allyl esters were fulfilled by employing a sodium borohydride-nickel chloride- methanol catalytic system with exceedingly simple manipulations and high functional group tolerability. Both of the reductive reactions may involve π-allylnickel intermediates generated from fresh nickel boride.
