Conversion of [Cp*IrCl 2 ] 2 to the imidocomplexes Cp*IrNR (R=t-Bu, SiMe 2 t-Bu, 2,6-Me 2 C 6 H 3 , 2,6-t-Pr 2 C 6 H 3 ). Surprisingly, these compounds are monomeric, but as expected they exhibit novel reactivity, including transfer of the NR group to electrophilic substrates
[Cp*IrCl 2 ] 2 转化为亚胺配合物 Cp*IrNR (R=t-Bu, SiMe 2 t-Bu, 2,6-Me 2 C 6 H 3 , 2,6-t-Pr 2 C 6 3)。令人惊讶的是,这些化合物是单体的,但正如预期的那样,它们表现出新的反应性,包括将 NR 基团转移到亲电子底物
Syntheses of Di- and Trinuclear Platinum Complexes with Multibridged Germanium Centers Derived from Unsymmetrical Digermanes
synthesized by the reaction of the zerovalent platinum complex [Pt(dppe)(η2-C2H4)] (dppe = 1,2-bis(diphenylphosphino)ethane) with the unsymmetrical digermane H3GeGeEt3 at a 3/2 molar ratio. The platinumcenters formed a triangular plane bridged by two germylyne ligands, one of which maintained the Ge–Gebond. To investigate the Pt3Ge2 cluster formation process, the phenyl-substituted digermanes HPh2GeGeMe3
The first complexes and cyclodimerisations of methylphosphaalkyne, PCMe, are reported to arise from its reactions with a range of platinum(0) complexes and [W(CO)5(THF)]. A number of differences between the chemistry of this phosphaalkyne and that of its bulkier analogues have been highlighted and explained on steric grounds.

The bissilyl complexes 3–6 were synthesized by reactions of the platinum(0) complexes [Pt(η2-C2H4)(diphos)] (1: diphos = dppe; 2: diphos = dcpe) with the disilanes 1, 1,2, 2-tetramethyldisilane and 1, 1,2, 2-tetraphenyldisilane via Si–Si bond activation. The molecular structures of 4 and 5 in the solid state are reported. The reaction of 2 with HPh2SiSiPh2H led to the immediate formation of the hydrido
