摘要：

The reaction of 1,5-Ph4P2N4S2 with Li[Et3BH] (1:2 molar ratio) in THF at -78-degrees-C yields the corresponding dianion, which reacts with CH2I2 to produce the novel bicyclic ring Ph4P2N4S2CH2 shown by X-ray crystallography to contain a methylene bridge between the two sulfur atoms of a P2N4S2 ring. The CH2 bridge is readily deprotonated by (n)BuLi to give the carbanion Ph4P2N4S2CHLi, which, upon treatment with iodomethane, produces Ph4P2N4S2CH(CH3). The dianion of 1,5-Ph4P2N4S2 can also be used to prepare eta-2-S,S' complexes of Ni and Pt and the S,S'-dimethyl derivative.
