The products of photodimerization of N-benzoylazacyclohex-2-ene-4-one (1) have been investigated by X-ray crystallography. Irradiation of a benzene solution of compound 1 leads to a mixture of head-to-head and head-to-tail, cis,anti,cis adducts, namely, cis,anti,cis-N,N′-dibenzoyl-3,12-diazatricyclo[6.4.0.02,7]dodecan-6,12-dione and cis,anti,cis-N,N′-dibenzoyl-3,9-diazatricyclo[6.4.0.02,7]dodecan-6,9-dione, compounds 2 and 3 respectively.
