A facile synthesis is described in which the Compounds N(SPPh2)(CH3SPPh2)](-), [N(SePPh2)(CH3SePPh2)](-), [N(SePPh2)(NCCH2SePPh2)](-) and [N(SPPh2)(NCCH2SePPh2)](-) have been obtained in good yield by alkylation of [N(QPPh(2))(2)](-) (Q = S or Se) or N(SPPh2)(SePPh2)](-) with CH3I OF ClCH2CN in CH3OH at room temperature. These compounds have been characterized by single-crystal X-ray diffraction and NMR spectroscopic techniques. All five compounds have similar structures in which a CH3 or NCCH2 moiety is bonded to an S or preferentially an Se atom of an anion to form a neutral molecule.
