Abstract
WHEREAS a variety of methods for the preparation of ethynylcarbinols from both saturated and unsaturated carbonyl compounds have been described1, we have traced only one reference2 in the literature to the preparation of diethynyl glycols, from dicarbonyl compounds and acetylene. While this work was in progress, Milas et al.2 reported the preparation of the diethynyl glycols from diacetyl and acetonyl-acetone.
