Abstract

On the basis of preferential complexation of oxygen or selenium atoms by different Lewis acids, it was expected that, depending on the Lewis acid employed, the title reactions would lead to selective formation of homoallyl ethers or homoallyl selenides. This has not been confirmed by experiment in almost all the reactions tried homoallyl ethers largely predominated, or were the exclusive allylation products, even when strongly ...
