Abstract : The present invention is directed to alpha-hydroxy-, alpha-alkyl;-substituted acetylene compounds. It is an object of the present invention to provide a new method for adding terminal acetylene groups to a molecule. Another object of the present invention is to provide a novel acetylenic end-capping agent for oligomers. A further object of the present invention is to provide a method for preparing novel acetylenic end-capping agents. In accordance with the present invention, there is provided a method for adding terminal acetylene groups to a molecule which comprises reacting a halogen-terminated molecule with the above-described end-capping agent followed by base-catalyzed cleavage.
