[Ni(P(o-C6H4S)(o-C6H4SC(CH3)NH2)(C6H5))2](ClO4)2 (2) with two thioiminium functionalities is derived from CH3CN solvent under anhydrous conditions. Moreover, thiaphospholanium salts, [(C6H5)P(C6H4SC(CH3)(NHCOCH3))(o-C6H4SH)](ClO4) (3) and [(C6H5)2-P(C6H4SC(CH3)(NH3))](ClO4)2 (5), can be obtained through a similar Pinner-type nitrile activation. These results demonstrate the possible intermediate of enzymatic nitrile transformation and also provide an approach to the preparation of 2-amino-1,3-benzothiaphospholanium derivatives.
