Abstract

Abstract: The mechanism of formation of the mesitylylene biradial (3) produced by short- wavelength photolysis of matrix-isolated mesitylene (1) has been investigated. The data rule out a mechanism involving the sequential formation of the biradical 3 via photolysis of the m- methylbenzyl radical 2. The data are most consistent with a mechanism in which the nascent H atom formed by initial scission of a benzylic carbon-hydrogen bond partitions between ...
