Abstract
Crystalline powder of all-trans-1,6-bis(4-R-phenyl)-1,3,5-hexatriene (R = C HO and CN) underwent intermolecular [2+2] photocycloaddition at the 1,2-pos ition of the triene to give mirror symmetric dimers. For the formyl derivat ive the presence of C-H . . .O hydrogen bonds was suggested by IR and C-13 CP/MAS NMR spectra.
