The paper describes a rapid and convenient route for the preparation of 2-halo-1,3- and -1,4-diethynylbenzenes (halogen = Cl, Br, I) starting from 2-nitro-1,3- and -1,4-diacetylbenzenes.The compounds are sensitive to light and decompose easily.Their preparation opens the way to the synthesis of widely substituted poly-(diethynylbenzene)-type polymers.Some were prepared and characterized for their stability and electrical properties, and the influence of halo-substituents examined.

A convenient two-step synthesis of bis(ethynyl)benzenes starting from the corresponding bis(acetyl)derivatives via chlorination of the carbonyl functions with PCl5 followed by dehydrochlorination with sodium amide in liquid ammonia is described.The new compounds obtained have been characterised by spectroscopic and elemental analysis.
