  摘要：

  Reactions of diphenylacetylene or dimethylacetylenedicarboxylate with Q2[Pd2R2Cl2(mu-Cl)2] (1) [Q = (PhCH2)Ph3P; R = 2,3,4-trimethoxy-6-formylphenyll give metallic palladium and 2,3-diphenyl-, or 2,3-dimethylcarboxylate-, 5,6,7-trimethoxyindenone (2 or 3). respectively whereas diphenylacetylene reacts with [PdR(bipy)(MeCN)]ClO4 (4), to give 2,3-diphenyl-5,6,7-trimethoxyindenol (5) and [Pd2 (OH)2(bipy)2](ClO4)2 (6). Catalytic synthesis of 5 is achieved by reaction of [HgR2], Ph2C2, and CuCl2 in the presence of (Me4N)2[Pd2Cl6] (molar ratios 1:2:2:0.1).
