2,5,5-Triphenyl-2-thiazolin-4-one (7) is transformed by P2S5 in boiling dioxane or xylene into N-(3-phenyl-2-benzo[b]thienyl)-thiobenzamide (10). The chloro substituted derivatives 16 and 17 of 7 react analogously but, in the case of 17, a by-product which is believed to be the desired 2-thiazoline-4-thione 18 is also formed. The latter may be isomerised subsequently to 20. The structure of 10 was
