Abstract

Lithioalkynyltnorganoborales generated from the corresponding propargylic acetals rearrange in the presence of boron trichloride thus opening an efficient and convenient route to a variety of homopropargylic alcohols free of the corresponding allenic isomers. Unexpectedly, the parent derivative leads exclusively to the allenic alcohol.
