  摘要：

  This work concerns the synthesis of [bis(dimethylgermyl)alkane]bis(triphenylphosphine)platine(II) and -(diphos)platine(II) Me2Ge(CH2)nGe(Me2)PtL2 (n = 2, L = PPh3 (1), diphos (2); n = l, L = PPh3 (3), diphos (4) and (tetramethyldigermyl)bis(triphenylphosphine)platine(II) and -(diphos)platine(II) Me2GeGe(Me2)PtL2 (L=PPh3 (5), diphos (6). 3 and 5 are obtained by cyclization of bis(dimethylgermyl)alkanes Me2(H)Ge(CH2)nGe(H)Me2 (n = 1 or 2) or 1,1,2,2-tetramethyldigermane Me2(H)GeGe(H)Me2 with (Ph3P)2PtC2H4. The polymeric structures [Me2Ge(CH)2)nGe(Me2)Pt(PPh3)2]m (n = 1 or 2) react with diphos to give the monomer complexes 2 or 4. IR and NMR examinations are reported. Various cleavage reactions with halogens and organic halides are described. Reactions of 2 with phenylacetylene and 1,2,4-triazolinediones afford new heterocycles arising- from formal addition of these unsaturated systems across the Ge-Ge bond of the tetramethyldigermetane Me2Ge(CH2)2GeMe2.

• Synthesis of α-germyl and α-silylcarboxylic acids and selected electrochemical oxidations

  日期：2012.6

  New alpha-germylcarboxylic acids, alpha-silyl-alpha-halocarboxylic and alpha-silyl-alpha-alkylcarboxylic acids including some known alpha-silyl(cycloalkyl)carboxylic acids have been prepared by different synthetic methods. The anodic oxidation in basic methanol of selected examples of these acids has been investigated under various experimental conditions to afford mainly oxidative degermylation/desilylation and decarboxylation products. Based on the emerged products, various mechanisms are suggested and discussed. (C) 2011 Elsevier B. V. All rights reserved.
