✦ Synopsis

The photocycloaddition of cis-and trans-1-(p-methoxyphenyl)-l-propene to C60 gives only the trans [2+2] adducts. Irradiation of the isolated adduct gives a mixture of cis-and trans-l-(pmethoxyphenyl)-l-propene and C60 cycloreversion products. These results exclude a concerted addition

and are consonant with a two step mechanism.
