In the reaction of thiourea with vicinal dibromides containing an aryl or carbonyl substituent at the α position to both bromine atoms in the presence of acetone 2,6-diamino-4,4-dimethyl-1,3,5-perhydrothiadiazine dihydrobromide is formed.Substitution of one of the substituents in the dibromide by a nitro group greatly changes the character of the transformations of thiourea.The presence of a carbonyl substituent at only one of the bromine atoms does not prevent retention of the diisothiuronium structure which forms.
