Michael reaction. 2-Mercaptobenzothiazole undergoes the Michael addition with activated unsaturated compounds such as methyl vinyl ketone, 2- (or 4-) vinylpyridine, divinyl sulphone, and 2-nitrobut-l-ene yielding N-substituted benzothiazoline-2-thiones [e.g. (70) or (71)]. The... [Pg.669]

Irradiation of benzothiazoline-2-thiones (34) and acrylonitrile affords 2-alkyhdenethiazoles (35) (Scheme 6). On the other hand, two products (36,37) are formed by the photoaddition of (34) with 1,1-disubstituted alkenes such as methacrylonitrile and methyl methacrylate. Aminothietanes (38) is proposed as intermediates in these photoreactions. Thioformaldehyde formed by the decomposition of the intermediate has been detected by its trapping by a diene. Photocycloaddition reaction of N-unsubstituted... [Pg.2172]
