  Reactions of the homoleptic acetonitrile complexes of palladium and platinum with diethylamine

  摘要：

  The homoleptic [M(MeCN)(4)](2+) cations (M = Pd, Pt) as the tetrafluoroborato derivatives were reacted with NHEt(2). The platinum species affords the amidino derivative {Pt[(E)-HN=C(NEt(2))Me](4)}[BF(4)](2), 1, as the only detected product of the addition of the amine to the coordinated nitrile. On the contrary, for [Pd(MeCN)(4)][BF(4)](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(NEt(2))Me](4)}[BF(4)](2). Consistent with these findings, PdCl(2)(MeCN)(2) reacts with NHEt(2) in acetonitrile yielding the substitution complex PdCl(2)(NHEt(2))(2), whereas the amidino complex cis-PtCl(2)[(E)-HN=C(NEt(2))Me](2), 3 was obtained from PtCl(2)(MeCN)(2). Complex 3 was characterized by X-ray diffractometry. (C) 2010 Elsevier B.V. All rights reserved.

  The reactions of cis-[PtCl2(NCMe)(2)] with a fivefold excess of the primary aliphatic amines RNH2 (R = Me, Et. Pr', Bu-t) in CH2Cl2 at - 10 degreesC afford in high yield the bis-amidine complexes cis-(PtCl2Z-N(H)=C(NHR)Me}(2)], where both amidine ligands assume the Z configuration. The corresponding reactions of trans-[PtCl2(NCMe)(2)] with RNH2 (R = Me, Et, Bu-t) give a mixture of the bis-amidine trans-[PtCl2Z-N(H)=C(NHR)Me}(2)] and the mono-amidine trans -[PtCl2(NCMe) Z-N(H)= C(NHR)Me}] derivatives, which could be isolated as pure products operating with a platinum nitrile complex:amine molar ratio of 1:50 or 1:1, respectively. The reaction of trans-[PtCl2(NCMe)(2)] with a 50-M excess of Pr'NH2 affords the bis-amidine bis-amine dicationic complex trans-[Pt(H2NPri)(2) Z-N(H)=C(NHPr')Me}(2)]Cl-2, which has been characterized also by X-ray diffraction analysis. The reactions of cis- and trans-[PtCl,(NCMe)21 with the secondary aliphatic amines R'R"NH yield the bis-amidine complexes cis- and trans-[PtCl2 E-N(H)=C(NR'R")Me}(2)] (R', R"=Et) and/or cis- and trans-[PtCl(NCMe)E-N(H)= C(NR'R")Me}(2)] (R', R"=Et, R'=Me. R"=Bu-t), where the amidine ligands have the E configuration. The compound trans-[PtCl2(NCMe)E-N(H)=C(NMeBut)Me] has been characterized by single crystal X-ray diffraction. All the complexes have been characterized by IR, H-1 and C-13 NMR spectroscopies. The Z or E configuration of the amidine ligand can be readily deduced by H-1 NMR data. (C) 2002 Elsevier Science B.V.
