The irradiation of a series of benzothiazolopyrazoline derivatives by UV Light in acidic medium using benzophenone as photo sensitizer resulted into rearranged pyrazolines. The effect of various substituents on the rate of photolysis and yield of the photoproducts were also studied.

Keywords :Irradiation, benzothiazolopyrazolines, photosensitizer, photolysis, photoproducts.
