Structure and chemistry of π-allyl palladium complexes from steroids
Abstract
The synthesis and structures of π-allyl palladium complexes prepared from vitamins D2 and D3 and from ergosterol, 7,8-didehydrocholesterol, and 3-epi-cholesterol are described. The mechanism of palladisation is discussed as well as the transformation of the complexes into conjugated trienes or allylic alcohols.
