Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 18583-60-3, is researched, Molecular C9H10BKN6, about Ethylene Polymerization Behavior of Tris(pyrazolyl)borate Titanium(IV) Complexes, the main research direction is pyrazolyl borate titanium complex ethylene polymerization catalyst; methylaluminoxane pyrazolyl borate titanium complex catalyst activity chain transfer.Synthetic Route of C9H10BKN6.
A set of Tp’TiCl3 and Tp’TiCl2(OR) complexes containing tris(pyrazolyl)borate ligands with diverse steric properties has been evaluated for ethylene polymerization under MAO (methylaluminoxane) activation conditions (Tp’ = HB(3-mesitylpyrazolyl)2(5-mesitylpyrazolyl)- (TpMs*), HB(3-mesitylpyrazolyl)3- (TpMs), HB(3,5-Me2-pyrazolyl)3- (Tp*), HB(pyrazolyl)3- (Tp), BuB(pyrazolyl)3- (BuTp)). The activity of Tp’TiX3/MAO varies in the order TpMs*TiCl3 (10c) > TpMsTiCl3 ≫ Tp*TiCl3, TpTiCl3, BuTpTiCl3, Tp*TiCl2(OtBu), Tp*TiCl2(O-2-tBu-C6H4). The activity of 10c/MAO is similar to that of Cp2ZrCl2/MAO. High MAO levels or addition of AlMe3 decrease the activity of 10c/MAO, probably due to coordination of AlMe3 to the active Ti species. The predominant chain transfer mechanism for 10c/MAO is chain transfer to AlMe3, which results in broad mol. weight distributions at low Al/Ti ratios (Al/Ti = 200-1000). At very high Al levels (10c/5000 MAO or 10c/1000 MAO/4000 AlMe3) bimodal mol. weight distributions comprising a major low mol. weight fraction (Mw/Mn ca. 3) and a minor high mol. weight fraction are observed, which suggests that several active species are present, only one of which undergoes efficient chain transfer to Al.
