  名称：

  Synthesis, coordination chemistry, and metal complex reactivity of (dimethylamino)methyl-substituted triarylphosphanes; X-ray study on [AuCl(PPh3−nArn)] (Ar=1-C6H3(CH2NMe2)2-3,5, n=1, 3; Ar=1-C6H4(CH2NMe2)-4, n=3)

  摘要：

  The synthesis of the first series of 4-mono and 3,5-bis(dimethylamino)methyl-functionalized triarylphosphanes of the general formula PPh3-nArn (Ar = 1-C6H3(CH2NMe2)(2)-3,5 (NC(H)N), n = 1 (ligand 2) or n = 3 (ligand 4); Ar = 1 -C6H4(CH2NMe2)-4 (NC(H)), n = 3 (ligand 7)) is described. These phosphanes were used for the construction of complexes of the form [AuCl(P)] and [PtCl2(P)(2)]. In these complexes selective coordination of phosphorus to the metal ion is observed. The P-31 NMR data show the formation of cis-Pt complexes, even in the case of triarylphosphane 4, which features a tris{3,5-bis(dimethylamino)methyl} substitution pattern. The structure of the gold complex of mono-3,5-functionalized triarylphosphane 2 in the solid state shows a striking resemblance to the structure of the corresponding complex [AuCl(PPh3)]. The solid-state structure of the AuCl complex of tris-4-functionalized ligand 7 differs from that of [AuCl(PPh3)] in the sign of the torsion angles. The amine functionalities in this class of gold compounds could be reacted selectively with either acid (HCl, H3PO4) to generate ammonium salts or with an alkylating agent (benzyl bromide) to afford benzyl ammonium salts, without the violation of the Au-P bond.

  Treatment of P(C6H4CH2NMe2-2)(3) (1) with 2 equiv. of CuX (2a X = Cl, 2b X = Br) produces the novel dicopper complexes [P(C6H4CH2NMe2-2)(3)]Cu2X2 (3a X = Cl, 3b X = Br) in high yields. The X-ray structure of 3b was determined. Crystals of 3b are orthorhombic, space group Pna2(1), with a = 19.280(4) Angstrom, b = 15.717(3) Angstrom, c = 11.201(2) Angstrom, V = 3394(1) Angstrom (3), Z = 4, and final R-1 = 0.0573 [I greater than or equal to 2 sigma (I)] for 2301 reflections used (1621 reflection with I greater than or equal to 2 sigma (I)) and 340 variables. The structure of 3b consists of two copper(I) centers of which one copper atom possesses a heavily distorted trigonal-pyramidal environment, while the other one is almost square-pyramidal coordinated; the Cu2Br2 segment gives rise to a situation, which may be considered as a contact ion pair between Cu+ and CuBr2-.
