Copper-catalyzed highly efficient hydrosilylation reaction of enynoates was developed.Under simple reaction conditions,various di-,tri- and tetrasubstituted racemic allene products could be obtained in high yields.The asymmetric 1,6-addition of silyl group to the (Z)-2-alken-4-ynoates could be achieved under mild reaction conditions to afford the silyl-substituted enantioenriched chiral allene products in good yields and with high enantioselectivities.
