Thioureas hypochlorite oxidation

Carbodiimides have been prepared by desulfurization of thioureas by metal oxides, by sodium hypochlorite,4 or by ethyl chloroformate in the presence of a tertiary amine by halogena-tion of ureas or thioureas followed by dehydrohalogenation of the N,N -disubstituted carbamic chloride 8 and by dehydration of disubstituted ureas using -toluenesulfonyl chloride and pyridine.7 The method described above is a modification of that of Campbell and Verbanc. ... [Pg.32]

Thioureas as are also oxidized with excess alkaline hypochlorite below 0 °C to give carbodiimides 24 in excellent yields." ... [Pg.14]
