Synthesis of Some 2,4-Hexadiyne and their Polymers

Abstract

Diacetylene monomers 2, 3 and 4 were synthesized using Hay coupling
procedure. They subjected to γ-ray irradiation resulted into polymer formation
compound (8) while compounds (3a-c) were unsuccessful towrd topochemical
polymerization. The corresponding acid chloride compound (5) was then condensed
with diamine affording polyamide 6 and 7. The above symmetrically substituted
1,3-diynes together with their polymers have been characterized by combination of
spectral methods IR,1HNMR, C13NMR and are discussed.
