Abstract

The reactions of methylaluminium dichloride, dimethylaluminium chloride, and trimethylaluminium with vinyl chloride have been investigated. Of themethylaluminium compounds investigated, the dichloride reacted most readily. This reaction, carried out in n-heptane as solvent or without a solvent, produces chiefly cuprene and isobutane and a number of hydrocarbon and chlorohydrocarbon by-products. Dimethylaluminium chloride and trimethylaluminium react with vinyl chloride much less readily than methylaluminium dichloride; propylene and its oligomers are the major products. The mechanisms of the reactions of the individual methylaluminium compounds with vinyl chloride have been discussed on the basis of the experimental reaction data and NMR spectra. The decomposition of vinyl chloride by the Ziegler-Natta original and modified systems has been considered.
