The paper describes a rapid and convenient route for the preparation of 2-halo-1,3- and -1,4-diethynylbenzenes (halogen = Cl, Pr, 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.

Abstract
The paper describes a rapid and convenient route for the preparation of 2-halo-1,3- and -1,4-diethynylbenzenes (halogen = Cl, Pr, 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
