The methylpalladium and ‐platinum complexes [Pd(AcNac)(PMe 3 )CH 3 ], [Pd(SacNac)(PMe 3 )CH 3 ], and [Pt(SacNac)(PMe 3 )CH 3 ] have been prepared from protonation reactions between AcNac [H 3 CC(O)CHC(NAr)CH 3 ; Ar = 2,6‐ i Pr‐C 6 H 3 = Dipp ( L 1 ); Ar = 2,4,6‐MeC 6 H 2 = Mes ( L 2 )] or SacNac [H 3 CC(S)CHC(NAr)CH 3 ; Ar = 2,6‐ i Pr‐C 6 H 3 = Dipp ( L 3 ); Ar = 2,4,6‐MeC 6 H 2 = Mes ( L 4 )] ligands and dimethyl–metal complexes of the composition [M(L′)Me 2 ] (M = Pd, L′ = tmeda = N , N , N ′ N′ ‐tetramethylethylenediamine; M = Pt, L′ = cod = 1,5‐cyclooctadiene) and PMe 3 in acetonitrile. Only one isomer was formed in each case and X‐ray crystallographic analysis showed that the PMe 3 co‐ligand is found in the cis position with respect to the sulfur or oxygen atom in all complexes.
