Abstract

Abstract Second-order rate constants are reported for the reaction of some YC 6 H 4 SnEt 3 compounds with mercuric halides in tetrahydrofuran, and show that the reaction is one of low selectivity. The substituent effects can be correlated only in terms of Hammett σ- constants, and the data for the meta-methoxy group are anomalous. The results indicate that the rate determining step involves reaction of a π-complex. Activation parameters are ...
