Synthesis and Characterization of Ruthenium Tris (pyrazolyl) borate Complexes Containing NN-, NS-, NNN-, and OO-Donor Co-Ligands

摘要

The synthesis and characterization of RuTp complexes containing the chelating ligands N,N'-bis (phenylmethylene)-1, 2-ethylenediamine (NN), 2-pyridinethiol (NS), N,N-bis-(2-(dimethyl-amino)ethyl)-N', N'-dimethyl-1, 2-ethanediamine) (N-crab), acetylacetonate( acac), and tetramethyl-ethylenediamine (tmeda) is described. While with NN, N-crab, acac, and tmeda mononuclear complexes are formed, a dimeric species is obtained with NS. X-ray structures of some complexes are given. The complexes featuring NN, acac, and tmeda react readily with terminal acetylenes to give vinylidene complexes.
