, p. 983 - 991 (2007/10/02)
Photoreaction of benzenecarbothioamide (1) in the presence of olefins gave isothiazole derivatives (10, 12, and 13) and 3,5-diphenyl-1,2,4-thiadiazole (11) under aerobic conditions, whereas under nitrogen atmosphere gave phenones (3 and 4).
PHOTOCYCLOADDITION OF ARYLCARBOTHIOAMIDES WITH UNSATURATED SYSTEMS. SYNTHESIS OF 3,5-DIARYL-1,2,4-THIADIAZOLES AND 3-ARYL-4,4,5,5-TETRAMETHYLISOTHIAZOLINES VIA PHOTOGENERATED NITRILE SULFIDES

On irradiation arylcarbothioamides (1) undergo, in the absence of oxygen, the Paterno-Buechi reaction with olefins followed by cleavage, whereas under aerobic conditions the photoreaction proceeds to give 4 and 5 probably via nitrile sulfide intermediates

2-Substituted 1,3-dithiol-2-yl azides, on thermolysis in refluxing toluene, give 3-substituted 1,4,2-dithiazines wich thermally extrude sulfur atom of the 4-position selectively to yield 3-substituted isothiazoles, while 2-unsubstituted 1,3-dithiol-2-yl azides undergo both ring expansion yielding 1,4,2-dithiazines and peculiar thermal dissociation into 1,3-dithiol-2-ylidene carbenes and hydrogen azide.
