Reaction of the complexes [Pt(S2COR)2] with K[S2COR](R = Et or Pri) followed by addition of [AsPh4]Cl generates [AsPh4][Pt(S2COR)3]. Variable-temperature 1H n.m.r. studies indicate rapid unidentate–bidentate exchange at ambient temperature. Attempted recrystallisation from CH2Cl2 or CDCl3, results in an intramolecular rearrangement to give [AsPh4][Pt(S2CO)(S2COR)]. Reaction of [Pd(S2COEt)2] with K[S2COEt]
配合物[Pt(S 2 COR)2 ]与K [S 2 COR](R = Et或Pr i)反应,然后添加[AsPh 4 ] Cl生成[AsPh 4 ] [Pt(S 2 COR)3 ]。可变温度1 H nmr研究表明,在环境温度下快速不对称交换。尝试从CH 2 Cl 2或CDCl 3重结晶,导致分子内重排得到[AsPh 4 ] [Pt(S 2 CO)(S 2 COR)]。[Pd(S 2 COEt)2 ]与K [S]的反应2 COEt]和[AsPh 4 ] Cl给出了[AsPh 4 4] [Pd(S 2 CO)(S 2 COEt)]作为主要产物。[Pt(S 2 COR) 2 ]与K [S 2 COR](R = Me或CH 2 Ph)和[AsPh 4 ] Cl的反应生成[AsPh 4 ] [Pt(S 2 CO)(S 2 COMe )]或[AsPh 4 ] 2 [Pt(S 2 CO) 2 ],在添加各种Lewis碱L(L
