Homogeneous platinum(II)-catalysed hydrogen exchange in the alkylbenzenes: relationship to simple alkane exchange
Abstract
Deuteriation in the side-chain of the long-chain alkylbenzenes using a homogeneous platinum(II) catalyst occurs predominantly at the α- and terminal carbon positions, isotope incorporation progressively decreasing from n-butyl- to n-nonyl-benzenes; in the side-chain of 1,1-dimethylpropylbenzene exchange is exclusively at the γ-position.
