11. The progress of the photo-reaction was monitored by electronic spectral change of the vibronic absorptions in 320-390 nm in benzene and an apparent photo-stationary state was attained after 6 h (50% consumption of 1a: ca. 4.5 h). The gradual dissociation was observed for the backward reaction to reach a stationary state after 12 h (50% consumption of 1b: ca. 4 h). No clear isosbestic point was observed due partially to the solvent system used.

From the elemental analyses, their compositions have been estimated as 1b·2 benzene, 1b·1.5 dichloromethane and 1b·2 chloroform, respectively.
