Intermolecular transfer of the alkyl ligands

NiCl(Et)(bpy) undergoes the disproportionation to produce an equimolar mixture of the dichloro and diethyl nickel complexes in THF at room temperature 

It is more facile than the reaction of NiBr(Ar)(bpy), whose disproportionation via intermolecular aryl ligand transfer requires polar solvents to assist Ni-halogeno bond activation as mentioned in a previous section. Methylplatinum complexes with monodentate phosphine, arsine and thioether hgands cause methyl ligand transfer leading to disproportionation and cis-trans isomerization [207] (Eq. 5.63). 

The reaction mixture contains dimethyl-, chloro(methyl)-, and dichloroplatinum complexes in a stahshcal molar raho. C 5-PtCl(Me)(PR3)2 isomerizes into the trans form during the reaction. 

Halogeno(trialkyl)palladium(IV) complexes with bipyridine and phenanthro-line ligand react with dimethylplatinum complex with the iV-ligand to cause transfer of the halogeno and the apical alkyl ligands of the Pd complex to Pt as 

Ni(II) and Ni(IV) complexes with chelating 2-acylphenolato ligand undergo several unique reactions including the transmetalation as mentioned below. The nickel(II) complex with a 2-acylphenoxido ligand, Ni[CO-C6H2(Me)(t-Bu)-
