from the reactions of [Pd2(μ-dppm)2Cl2] with Na2[Cr2(CO)10] or [Et4N][HCr(CO)5], and of the latter anion with 3. Whereas reaction of this anion with trans-[PdCl2(PEt3)2] led to reduction to palladium metal, trans-[PtCl2(PEt32] was converted into [Pt4(μ-CO)5(PEt34] (79% yield).

配体的残留酸度,它们充当[Fe(CO)4 ] 2-的前体。在[Et 4 N] [HM(CO)5 ](MCr,W)和[PtCl 2(dppm)]之间的反应中发生
氢化物转移,然后进行分子重排,得到[Pt 2(μ-H) (μ-dppm)2 H 2 ] [
MCl(CO)5 ]。从[Pd 2(μ-dppm)2 Cl 2 ]与Na 2 [Cr 2(CO)10 ]或[Et 4 N] [ HCr(CO)5 ],和后者的阴离子为3。该阴离子与反式-[PdCl 2(PEt 3)2 ]的反应导致还原为
钯金属,而反式-[PtCl 2(PEt 3 2)则转化为[Pt 4(μ-CO)5(PEt
