  New highly water-soluble rhodium complexes bearing 1,3,5-triaza-7-phosphaadamantane (PTA) and/or tris(hydroxymethyl) phosphine (THP)

  摘要：

  A family of cationic and neutral highly water-soluble rhodium complexes [Cp*Rh(PTA)(3)]Cl-2 (1), [Cp*RhCl2(THP)] (2), [Cp*RhCl(THP)(2)]Cl (3), and [Cp*RhCl(PTA)(THP)] Cl (4) have been synthesised and fully characterised [PTA = 1,3,5-triaza-7-phosphaadamantane; THP = tris(hydroxymethyl) phosphine]. Their water-solubility increases as the number of the phosphines coordinated to the metal centre is increased. The X-ray crystal structure of compound 2 was obtained and shows the presence of intermolecular hydrogen bonding. NMR speciation studies of [Cp*RhCl2(PTA)] in deuterated water show the existence of several equilibria involving substitution processes in which the water molecules can substitute both chloride and PTA ligands.

  Synthesis and reactivity of rhodium(III) pentamethylcyclopentadienyl complexes of N–B–PTA(BH3): X-ray crystal structures of [Cp∗RhCl2{N–B}–PTA(BH3)] and [Cp∗Rh{N–B–PTA(BH3)}(η2-CH2=CHPh)]

  摘要：

  The reaction between 1-boranyl-1,3,5-triaza-7-phosphaadamantane ligand N-B-PTA(BH(3)) and [Cp*RhCl(mu-Cl)](2) affords [Cp*Rh{N-B-PTA(BH(3))}Cl(2)] (3) or [Cp*Rh{N-B-PTA(BH(3))}(2)Cl]Cl (5) containing one or two P-bonded boronated PTA ligands. The hydride [Cp*Rh{N-B-PTA(BH(3))}H(2)] (8) was also obtained by reaction of 3 with NaBH(4) and alternatively by direct hydroboration of [Cp*Rh(PTA)Cl(2)] with excess NaBH(4). Moderately slow hydrolysis of the N-boranyl rhodium complexes affords dihydrogen, H(3)BO(3) and the corresponding PTA derivatives, including the water-soluble dihydride [Cp*Rh(PTA)H(2)] (9). Finally, the reaction of 8 with electron poor alkynes gives the alkene complexes [Cp*Rh{N-B-PTA(BH(3))}(eta(2)-CH(2) = CHR)] (R = Ph, 10; C(O)OEt, 11) as a mixture of rotamers eta(2)-coordinated to rhodium without affecting the N-BH(3) moiety. The X-ray crystal structures of 3 and 10 were also obtained and are here discussed. (C) 2008 Elsevier B. V. All rights reserved.

• Counterion-dependent deuteration of pentamethylcyclopentadiene in water-soluble cationic Rh(iii) complexes assisted by PTA

  [Cp*RhCl(PTA)2]X (PTA = 7-phospha-1,3,5-triazaadamantane) undergoes an H/D exchange process between the methyl groups of Cp* and D2O whose rate depends on the coordinating ability of the counterion X−. Kinetic studies and DFT calculations indicate that deuteration involves the abstraction of a Me-Cp* proton by a coordinated OH−; the formation of the latter seems to be facilitated by the presence of the N-basic centers of PTA.

  [Cp*RhCl(PTA)2]X（PTA = 7-磷-1,3,5-三氮杂金刚烷）在 Cp* 的甲基和 D2O 之间经历了一个 H/D 交换过程，其速率取决于反离子 X- 的配位能力。动力学研究和 DFT 计算表明，氘化涉及配位 OH- 对 Me-Cp* 质子的抽取；PTA 的 N 碱中心的存在似乎促进了后者的形成。

  Reaction of the dimer [(eta(5)-C5Me5)RhCl(mu(2)-Cl)](2) with 2 or 4 equiv of the water-soluble phosphine 1,3,5-triaza-7-phosphatricyclo[3.3.1.1] decane (pta) affords [Rh(eta(5)-C5Me5)(pta)Cl-2] and [Rh(eta(5)-C5Me5)(pta)(2)Cl] Cl, respectively. Both complexes have been characterized in solution by NMR spectroscopy and in the solid state by single-crystal X-ray diffraction, the latter as the chloride and BPh4- salts. In addition, the rhodium(I) complexes [Rh(eta(5)-C5Me5)(CO)(pta)] and [Rh(eta(5)-C5H5)(pta)(2)] have been prepared lfrom [Rh(eta(5)-C5Me5)(CO)(2)] and [Rh(eta(5)-C5H5)(PPh3)(2)], respectively, by reaction with pta. An in vitro evaluation of these compounds, together with [Os(eta(6)-C10H14)(pta)Cl-2] and the well-characterized antimetastasis drug [Ru(eta(6)-C10H14)(pta)Cl-2], RAPTA-C, was undertaken using HT29 colon carcinoma, A549 lung carcinoma, and T47D breast carcinoma cells. In the HT29 cell line, the two nearest congeners to [Ru(eta(6)-C10H14)(pta)Cl-2], viz., [Rh(eta(5)-C5Me5)(pta)Cl-2] and [Os(eta(6)-C10H14)(pta)Cl-2], demonstrated very similar cytotoxicity profiles. [Rh(eta(5)-C5Me5)(pta)Cl-2] proved significantly more cytotoxic in A549 cells and [Rh(eta(5)-C5Me5)(pta)(2)Cl] Cl 3-fold more cytotoxic in T47D cells, both relative to RAPTA-C. These data suggest that the development of organometallic anticancer drugs based on the neighboring elements to ruthenium should not be overlooked.
