Abstract

In this paper we present the details12 of SET-initiated cleavage of PhSeSePh to electrophilic an selenium species (PhSe+) using'DCN* as electron acceptor and ita utilization in selenenylation reactions as depicted in Scheme I. Steady-state analysis of fluorescence quenching, dependence of the PhSeSePh quantum yield in the selenenylation reaction on ita concentration, and trapping of the resultant PhSe+ for synthetic purposes provides ...
