Evidence for the formation of unscavengeable diradical intermediates in the photolysis of cis- and trans-3-ethyl-2-propylthietan
Abstract
The gas-phase photolysis of either cis-or trans-3-ethyl-2-propylthietan produces but-1-ene, cis- and trans-hept-3-ene, and isomerized substrate, the yields of which are unaffected by adding NO or CO2; a short-lived diradical intermediate is indicated.
