The title compounds were prepared by the Erlenmeyer synthesis and irradiated with or without a Pyrex filter using 450 W medium pressure mercury arc lamp. Cis-trans isomerization was the major reaction under pyrex filtered condition, whereas irradiation without a Pyrex filter resulted in decarbonylation, followed by trapping of the ketenimine intermediate by protic solvents.
