Abstract
The title compound yields a photodimer on u.v. irradiation, and not a phototrimer as described in the literature. This dimer has been shown to be 2,9-dibenzyl-6,12-diphenyl-dispiro[4.1.4.1]dodecan-1,8-dione (XII); its stereochemistry has been elucidated by chemical and spectroscopic methods.Keywords
