A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine), molecular formula is C36H28OP2. In a Article，once mentioned of 166330-10-5, Safety of (Oxybis(2,1-phenylene))bis(diphenylphosphine)
A series of tridentate anilido-imine [N,N,O] ligands 2-(2-(R 12-2,6-C6H3NH)C6H 4)HC=N(4-tBu-6-R2-C6H2OH) [R1 = Me, R2 = tBu (LaH 2); R1 = Et, R2 = tBu (L bH2); R1 = iPr, R2 = tBu (LcH2); R1 = Me, R2 = Ad (LdH2); R1 = Et, R2 = Ad (L eH2); R1 = iPr, R2 = Ad (LfH2)] were synthesized and characterized. Reaction of the free ligand LdH2 with TiCl4 in toluene at low temperature affords the zwitterionic complex Ld+H 2Ti-Cl4 (1d). The zwitterionic complex can be dissolved in THF to form THF-solvated complex 1d?. Heating 1d in toluene at 40 C affords the neutral complex LdHTiCl3 (2d) by losing a HCl. Complex 2d can be fully converted to the final complex L dTiCl2 (3d) at 140 C under vacuum by losing another HCl. Complexes 3a-3c, 3e, and 3f were also synthesized in high yields in the same one-pot procedure. All complexes were characterized by 1H and 13C NMR spectroscopy, and the molecular structures of 1d?, 3b, 3d, and 3e were determined by single-crystal X-ray diffraction analysis. The titanium centers in complexes 3b, 3d, and 3e are five-coordinated with a geometry situated between trigonal bipyramid and square pyramid. Upon activation with alkylaluminum and Ph3C+B(C6F 5)4-, complexes 3a-3f exhibit moderate catalytic activity for ethylene polymerization.
