Considerable attention has been focused on the photochemistry of five-membered heterocyclic ring systems. 1 By far the greatest area of activity in this field has been a study of the photoisomerization of the heterocyclic nucleus. The literature on the photoprocesses observed with isothiazoles has r

β¦ Synopsis
German workers' have repcrted recently that the reaction of 3,4-dichlorc-1,2-bensisothiasole with sodium alkcxides or with secondary smines gives the expected nucleophilic substitution product, together with small amounts of material formed by fission of the isothiaeole ring.

Fast atom bombardment mass spectral examination of molecules containing a 1,2-benzisothiazole ring, using a thiol reducing agent matrix, promotes reductive ring opening of the benzisothiazole ring, giving an [M+H] + two daltons higher than expected. Measurements using a non-reducing matrix produce t
