Selectivity in reactions of alkyl-aryl-transition-metal complexes with electrophiles

The new methylarylmetal complexes cis-[AuMe2Ph(PPh3)], cis-[AuMe2(4-MeC6H4)(PPh3)], [PtMe(4-MeC6H4)(C8H12)], cis-[PtMePh(PMePh2)2], and cis-[PtMe(4-MeC6H4)(PMe2Ph)2] have been prepared and characterized. In reactions with electrophilic reagents such as HCl, HgCl2, and [PtI2(PMe2Ph)2], the complexes undergo selective cleavage of a methyl-metal bond (e.g., cis-[PtMePh(PMePh2)2]) or an aryl-metal bond (e.g., cis-[AuMe2Ph(PPh3)], [PtMe(4-MeC6H4)(C8H12)]). From the selectivity observed and from studies of relative rates of reaction, it is argued that the SE2 mechanism leads to selective aryl-metal bond cleavage and that a different mechanism, probably involving an oxidative-addition-reductive-elimination sequence, leads to selective methyl-metal bond cleavage.
