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.
Substituent Interaction with Ring Sulfur in some Heterocyclic Compounds

The infrared carbonyl absorptions of 7-acetyl-1,2-benzisothiazoles are similar to 7-acetylbenzothiophenes, but are lower by approximately 15 cm-1 than the corresponding benzofurans.The reasons for this are discussed.
