%X Oxidation of benzoylthiourea with bromine gives initially N1,N3-dibenzoyl-&#945;,&#945;-dithiobisformamidine dihydrobromide (5) which, on recrystallization or treatment with polar solvents, rearranges and cyclizes with elimination of ammonium bromide or sulphur to give derivatives of 3H-1,2,4-dithiazole and 1,2,4-thiadiazole respectively. The former reaction is unprecedented in thiourea oxidations and occurs exclusively under suitably chosen conditions.
