A superior method of conjugate allylation: The transmetalation of allyltin compounds with TaCl5 yielded active tantalum reagents for conjugate addition to enones. Even bulky allyl moieties could be introduced to enones in this manner (see scheme). Both cyclic and acyclic enones reacted facilely under extremely mild conditions.

A conjugate addition of allylsilanes to α,β-unsaturated ketones was effectively promoted by a catalytic amount of trityl perchlorate to give the corresponding Michael adducts in good yields.
