The paper is dedicated to Professor Amos B. Smith, III, on the occasion of his 70th birthday. Abstract An efficient one-pot procedure for the synthesis of propargyl alcohol derivatives from allyl alcohol derivatives has been developed. The key to this transformation from a C–C double bond to a C–C triple bond is that hydrogen bromide elimination from 1,2-dibromoalkanes that contain a neighboring oxygen
