    • A process for the manufacture of heteroleptic complexes of a transition metal M having the general formula [M(L) n L'] wherein M is Ir, Rh, Pt or Pd and n is 2 for M = Ir or Rh and n is 1 for M = Pt or Pd and L is a bidentate cyclometallated ligand coordinated to the metal M through covalent metal-C and dative donor-atom-metal bonds,by reacting a halo-bridged dimer of general formula [L n M(µ-X) 2 )ML n ] with a bidentate ligand compound of formula L'-H or a halo-bridged dimer of general formula [L' n M(µ-X) 2 -ML' n ] with a ligand compound of formula L-H where (µ-X) represents a bridging halide in a solvent mixture of an organic solvent and water comprising more than 25 vol% of water at a temperature of from 50 to 260°C in the presence of from 0 to 5 molar equivalents relative to the number of moles of halide X-ion introduced into the reaction mixture through the halo-bridged dimer of a scavenger for halide X-ion and in the presence of from 0 to 0.8 moles, based on the molar amount of transition metal in the halo-bridged dimer of an added salt and of from 0 to 10 vol%, based on the total volume of the solvent mixture, of a solubilisation agent increasing the solubility of the halo-bridged dimer in the reaction mixture.
    • 制备具有通式[M(L)nL']的过渡金属M的杂光配合物的方法,其中M为Ir,Rh,Pt或Pd,对于M = Ir或Rh,n为2,n为1,n为1, M = Pt或Pd,L是通过共价金属-C和二价供体 - 原子 - 金属键与金属M配位的二齿环金属化配体,通过使通式[LnM(μ-X)2)的卤代桥连的二聚体, MLn]与式L'-H的双齿配体化合物或通式[L'nM(μ-X)2-ML'n]的卤代桥连二聚体与式LH的配体化合物反应,其中(μ-X) 在相对于卤化物的摩尔数为0至5摩尔当量的存在下,在50至260℃的温度下,在有机溶剂和包含超过25体积%的水的溶剂混合物中的桥联卤化物 通过用于卤化物X离子的清除剂的卤代桥连的二聚体将X离子引入反应混合物中,并且在0至0.8摩尔存在下,基于反式摩尔数 在加成盐的卤代桥连二聚体中的金属和基于溶剂混合物的总体积的0至10体积%的增溶剂,其增加了卤代桥连二聚体在反应混合物中的溶解度。
