โœฆ Synopsis

A [3 + 2]-Photocycloaddition of 9,10-Dicyanophenanthrene to 1,3-Butadiene.

-The product ratio is influenced by dilution of the reaction mixture, 9-fluorenone as additive and the change to benzene as solvent. In all cases, the yield of product (III) decreases (0% yield in benzene solution). Mechanistical aspects are discussed.

The (2 + 21 photocycloaddition of 2-(trimethylsilyloxy)-1,3-butadiene to a number of 2-cycloalkenones proved to be quite a general reaction leading to good yields of the cycloadducts (Table ). This finding is surprising since dienes, in general, are better known as quenchers of enone triplets rather
