Alkylation of aromatic compounds with allylchlorosilanes

Abstract

1. It was shown that aromatic compounds can be alkylated by allylchlorosilanes in presence of aluminum chloride. 2. The alkylation of aromatic compounds with allylchlorosilanes leads to products of branched structure of the type , in contrast to the products of alkylation with chlorovinylsilanes, which have the unbranched structure . 3. In reactions with benzene derivatives silylalkyl groups are oriented in the para-position relative to substituents of the first kind (the usual “ortho-para orientants”). 4. Under the alkylation conditions allyltriorganosilanes polymerize with opening of the double bond.
