| 摘 要： | Two ligand bridged binuclear titanium complexes Ti2（bppda）3（NMe2）2·3THF （1） and Ti2（bppda）3（NEt2）2·3THF （2） and one bis-ligand coordinated mononuclear complex Ti（bppda）2 （3） （ligand- HEbppda=N,N＇-Bis（2-pyrrylmeth- ylidene）-1,2-phenylenediamine） were synthesized by adjusting the ratio of the starting materials and the reaction speed. The complexes were fully characterized with NMR, elemental analysis and X-ray crystal diffraction. The catalytic activity of the complex 1 to phenylacetylene hydroanilination reaction was also investigated.

| Abstract: | Two ligand bridged binuclear titanium complexes Ti2(bppda)3(NMe2)2·3THF ( 1 ) and Ti2(bppda)3(NEt2)2·3THF ( 2 ) and one bis‐ligand coordinated mononuclear complex Ti(bppda)2 ( 3 ) (ligand: H2bppda?N,N′‐Bis(2‐pyrrylmeth‐ylidene)‐1,2‐phenylenediamine) were synthesized by adjusting the ratio of the starting materials and the reaction speed. The complexes were fully characterized with NMR, elemental analysis and X‐ray crystal diffraction. The catalytic activity of the complex 1 to phenylacetylene hydroanilination reaction was also investigated. |
