V. Beneteau et al., RAPID SYNTHESIS OF 2-CYANOBENZOTHIAZOLES FROM N-ARYLIMINODITHIAZOLES UNDER MICROWAVE IRRADIATION, Synthetic communications, 27(13), 1997, pp. 2275-2280
Microwave irradiation of neat N-arylimino-1,2,3-dithiazoles 2 in screw
-capped glass vials gives 2-cyanobenzothiazoles 3, rapidly and cleanly
in good yield.
