Stereodynamic protection of a carbonyl group by two benzene rings against interaction with a triplet n→π* quencher in the photochemical reaction of 5,6,7,12,13,14-hexahydro-6,13-methanodibenzo[a,f]cyclodecen-15-one
Abstract
In the photolysis of the flexible 5,6,7,12,13,14-hexahydro-6,13-methanodibenzo[a,f]cyclodecen-15-one (1), the two annulated benzene rings protected the carbonyl group against interaction with a triplet quencher such as naphthalene.
