The photocycloaddition of some difluoro[(methylamino-κN)alkenonato-κO]boron complexes 1 with arylalkenes 2 is discussed. The resulting [2+2] photoaddition gave the cyclobutane and azetidine derivatives (Schemes 1, 3, and 5). Rearrangements of the cyclobutane gave 1,5-diketones derivatives (Schemes 2, 4, and 5). The yields of the photoadducts were governed by the reduction and oxidation potentials.
