The reaction of solvent substituted MoO2X2(S) 2 (X = Cl, S = THF; X = Br, S = DMF) complexes with one equivalent of bidentate nitrogen donor ligands at room temperature leads within a few minutes to the quantitative formation of complexes of the type [MoO2X 2L2] (L = 4,4?-bis-methoxycarbonyl-2,2?- bipyridine, 5,5?-bis-methoxycarbonyl-2,2?-bipyridine, 4,4?-bis-ethoxycarbonyl-2,2?-bipyridine, 5,5?-bis- ethoxycarbonyl-2,2?-bipyridine). Treatment of the complexes [MoO 2Cl2L2] with Grignard reagents at low temperatures yields dimethylated complexes of the formula [MoO 2(CH3)2L2]. [MoO2Br 2(4,4?-bis-ethoxycarbonyl-2,2?-bipyridine)], [MoO 2Br2(5,5?-bis-methoxycarbonyl-2,2?-bipyridine) ] and [MoO2Br2(5,5?-bis-ethoxycarbonyl-2,2?- bipyridine)] have been exemplary examined by single crystal X-ray analysis. The complexes were applied as homogenous catalysts for the epoxidation of cyclooctene with tert-butyl hydroperoxide (TBHP) as oxidising agent under solvent-free conditions. The complexes containing L = Cl have been additionally investigated with room temperature ionic liquids (RTILs) as solvents. The catalytic activity of the [MoO2X2L2] complexes in olefin epoxidation with tert-butyl hydroperoxide is on average very good. The main advantage of the synthesised complexes in comparison to previously reported complexes is their high solubility. This good solubility is apparently the reason that the catalytic potential of the compounds can unfold. The turnover frequencies (TOFs) in RTILs are even higher, showing the performance of the catalysts under optimised conditions.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: Diethyl [2,2′-bipyridine]-5,5′-dicarboxylate, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1762-46-5, in my other articles.
