Ligand Bridged and Bis-ligand Coordinated Titanium Complexes： Synthesis, Structure and Relevance to Phenylacetylene Hydroanilination Catalysis

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.
