NMR (1H, 13C, 31P). The crystal and molecular structures of 1, 2, 4–6 were determined by single-crystal X-ray diffraction. All compounds are monomeric and the N atom of the pendant CH2NMe2 arm is strongly coordinated to the tellurium atom. The organophosphorus ligands are monodentate, thus resulting in a T-shaped coordination geometry around tellurium.

only by a single pathway, specifically, reducing the cation of the primary iminium salt on the C–Br bond. New iminium salts were synthesized and converted into the corresponding aldehydes and imines. The aldehydes synthesized were converted into acetals and five-membered heterocyclic compounds.

confirmed by X-ray crystallographic study in the solid state. Reaction between [AuS2PPh2]2 and [Au(CH2)2PMe2]2 in CH2Cl2 solution leads to a ligand transfer reaction to form the hetero-bridged complex [Au2(CH2)2PMe2S2PPh2}] (3a) in high yield. Additionally, the latter complex reacts with Cl2 to form the oxidativeaddition product [Au2Cl2(CH2)2PMe2S2PPh2}] (4), the first gold(II) complex with a S-P-S
The reactions between SnCl2 and [Ph2P(S)S]2, Ph2P(S)SH and Ph2PS2NH4, respectively, were investigated by multinuclear (1H, 13C, 31P, 119Sn) NMR spectroscopy and the results are discussed. The previously reported cis-dichlorobis(diphenyldithiophosphinato)tin(IV) was isolated as C12Sn(S2PPh2)2 · 0.5(CH3)2CO and its crystalstructure was determined by X-ray diffractometry. The dithiophosphinato groups
