Preparation and molecular sturcture of 1-chloro-3,5-diphenyl-1,2,4,6-thiatriazine; reduction of Ph2C2N3SCl and the e.s.r. spectrum of the Ph2C2N3S)· radical
Abstract
The reaction of benzamidine wiht S3N3Cl3 yields 1-chloro-3,5-diphenyl-1,2,4,6-thiatriazine, whose molecular structure has been determined by X-ray crystallography; reduction of Ph2C2N3SCl with triphenylantimony yields the radical species (Ph2C2N3S)· characterized by its e.s.r. spectrum.
