Abstract

Transmetalation of alkenyl zirconocenes 2 to the corresponding organozinc compounds 3 occurs rapidly and at low temperature in the presenceof stoichiometric amounts of commercially available dimethyl- or diethylzinc. Subsequent addition of aldehydes provides an in situ protocolfor the conversion of alkynes 1 into allylic alcohols 5 in good to excellent yields.
