What is Evidence for CC coupling between two mutually cis carbon ligands, η3-crotyl and aryl in organopalladium(II) complexes about?

Some (~3-crotyl)(2,5-dichlorophenyl)palladium(ll) complexes containing phosphine and phosphite ligands Pd(~-CH2CH-CHMe) (At)(PR3) (Ar--C6H3CI2-2,5) were isolated as crystalline solids or generated in solution. These existed as a mixture of two geometrical isomers arising from a different way of relative disposition of the crotyl-methyl group and the aryl ligand. The electronic nature of the PR3 ligand controlled the relative rates of the interconversion between the two isomers and the reductive elimination of the complexes whieh released MeCH=CHCH2Ar and CH2=CHCH (Me) (Ar). Electron-withdrawing phosphite ligands were particularly effective in enhancing the reduetive elimination rate, making the contribution of the isomerization path almost negligible and allowing the formation of two coupling products to be followed separately by spectrcscopic means. These observations demonstrated the occurrence of C--C coupling between mutually cis carbon ligands in (~3-allyl)(hydrocarbyl)palladium(II) complexes. The v(-crotyi complex, Pd(7/~-CH2CH=CHMe) (Ar) (dppen) (dppen -cis-Ph2PCH=CHPPh2) was isolated and shown to exist as a sole regio-isomer in solution. Reductive elimination of this ~/I-cr
