Abstract: Abstract Tin reduction of 3,4,4,5-tetrachloro-4 H -1,2,6-thiadiazine afforded perchloro-9-thia-1,5,8,10-tetraazaspiro[5.5]undeca-1,4,7,10-tetraene (10%) and 3,5-dichloro-4 H -1,2,6-thiadiazine-4-thione (27%), the structures of which were supported by single crystal X-ray crystallography. Treating the tetrachlorothiadiazine with Ph 3 P (1Â equiv.) afforded… read more here.
