✦ Synopsis

New Syntheses of Aryl Isothiocyanates.

-A new method for converting arylamines (II) into isothiocyanates based on the cleavage of stable arylimino-1,2,3-dithiazoles (III) is accomplished. EtMgBr and NaH prove to be appropriate reagents for this transformation. The cleavage proceeds via isolable cyanothioformanilides [cf. (V)]. -(BESSON, T.;
