Abstract

The reaction of 2,2,6,6-tetramethylpiperidin-1-oxyl (1) with Cp2TiEtCl (2) has been studied. The consumption of1 and evolution of gaseous products (ethane, ethylene) proceed with autoacceleration. Increasing the1 : 2 molar ratio leads to inhibition of the autoacceleration. The fact that the yield of ethane is higher than that of ethylene indicates that the reaction proceedsvia SR2 substitution of the ethyl group in Cp2TiEtCl for radical1. The mechanism of the substitution is synchronous, A kinetic model of the reaction has been proposed and substantiated.
