Reactions of the homoleptic acetonitrile complexes of palladium and platinum with diethylamine
The homoleptic [M(MeCN)4]2+ cations (M – Pd,Pt) as the tetrafluoroborato derivatives were reacted with NHEt2. The platinum species affords the amidino derivative {Pt[(E)-HN=C(NEt 2)Me]4}[BF4]2,1, as the only detected product of the addition of the amine to the coordinated nitrile. On the contrary, for [Pd(MeCN)4][BF4]2 competition between the substitution of the nitrile and addition of the amine to the nitrile group is operative: by carrying out the reaction in acetonitrile as solvent, complete conversion was obtained to the crystallographically defined {Pd[(E)-HN=C(NEt2)Me]4}[BF4]2. Consistent with these findings, PdCl2(MeCN)2 reacts with NHEt2 in acetonitrile yielding the substitution complex PdCl 2(NHEt2)2, whereas the amidino complex ris-PtCl2[(E)-HN=C(NEt2)Me|2, 3 was obtained from PtCl2(MeCN)2. Complex 3 was characterized by X-ray diffractometry.
