1994 photochemistry, radiation chemistry, chemoluminescence photochemistry, radiation chemistry, chemoluminescence O 0160 -062Phototransposition Chemistry of Phenylisothiazoles and Phenylthiazoles. Part 1. Interconversions in Benzene Solution.-The title compounds (I)-(VI) undergo phototransposition by permutation pathways. A mechanism involving initial electrocyclic ring closure and sigmatropic shift of sulfur around the four sides of the azetine ring is discussed. -(PAVLIK, J. W.; TONGCHAROENSIRIKUL, P.; BIRD, N.
