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.
