Abstract Tetramethyldiphosphinomethane (CH3)2PCH2(CH3)2 (1a) reacts with HCl/ether to form the mono-and bisquaternary salts [(CH3)2PCH2P(H)(CH3)2]Cl (2) and [(CH3)2(H)PCH2P(H)(CH3)2]Cl2 (3), respectively. The system 1a/HCl, incorporating 1 a/2/3, represents a useful tool for studying the appearance of XnAA′X′n-spin type systems. These compounds are also prototypes for a variety of other mono-or bis-phosphonium salts, which are formed in the reactions of the diphosphines (CH3)2PCH2PR2 (R = CH3, t-C4H9, C6H5) (1a-c) with (CH3)2CO + HCl, CH3I, t-C4H9Br, C6H5COCl, (CH3)2PCl and Br(CH2)nBr (n = 1, 2). Heterocycles are not obtained. The dioxide 14 and the disulfide 15 are also described. Some properties and spectroscopic data (IR, 1H, 31P and 13C NMR) of 26 new compounds are reported and briefly discussed.
