Abstract

The uncatalysed reactions of phenylacetylenes with arsenic trichloride have been shown to give 1:1 trans~additon products whilst the acetylenic acids and their esters give complex cyclic adducts.

The reactions provide a novel route to compounds like B-chloro-(p-methylstyryl)diphenylarsine, cis-(p-styryl)diphenylarsine and p-chloro-(p-chlorostyryl)dichloroarsine and in all tvelve novel organo-arsenic compounds have been prepared.

The stereochemistry of the 1:1 trans-adducts and their
derivatives have been established and an attempt has also been
made to determine the reaction mechanism from spectroscopically
obtained kinetic data.
