摘要

Abstract The coupling of alcohols with alkenyl-and alkynylboron dihalides with high olefin stereoselectivity is described. The reaction provides a facile route to internal acetylenes. Notably, the allylation of propargylic alcohols mediated by boron trichloride proceeds smoothly at room temperature and gives excellent regioselectivity.
