Copper(I) [Cu2(μ-Br)2(tBuImCH2pyCH2L)] n (L = OMe, NEt2, NHtBu) compounds supported by flexible functionalized NHC-based polydentate ligands have been prepared in a one-pot procedure reacting the corresponding imidazolium salt with an excess of copper powder and Ag2O. An X-ray diffraction analysis has revealed that [Cu2(μ-Br)2(tBuImCH2pyCH2NEt2)] is linear coordination polymer formed bimetallic [Cu(μ-Br)]2 units linked lutidine-based NHC-py-NEt2 ligand, which acts as heteroditopic ligand...
An Ir–NHC compound catalyzes the borrowing-hydrogen reduction of nitroarenes into<italic>N</italic>-methyl amines with methanol through a direct mechanism.
The iridium(I) complexes [IrBr(cod)(κC-tBuImCH2PyCH2NRR')] (NRR' = NEt2, NHtBu) have been prepared by reaction of the corresponding functionalized imidazolium salt with appropriate dinuclear compound [Ir(µ-OR)(cod)]2 (R OMe, OEt). These compounds react H2(g) (5 bar) to afford pincer iridium(III) dihydrido [IrBrH2(κ3C,N,N'-tBuImCH2PyCH2NRR')] in good yields. efficiently catalyzed β-alkylation a series secondary alcohols and N-alkylation range aniline derivatives primary alcohols,...
Experimental and theoretical studies give support for an iridium-catalyzed C–N bond formation.
A set of neutral [IrBr(L2)(κC-tBuImCH2PyCH2OMe)] and cationic [Ir(L2)(κ2C,N-tBuImCH2PyCH2OMe)]PF6 (L2 = cod, (CO)2) Ir(I) compounds featuring a flexible lutidine-derived polydentate ligand having NHC −OMe as donor functions have been evaluated catalyst precursors for the N-methylation aniline using methanol both reducing agent C1 source. The carbonyl complexes are somewhat more active than related diene with compound [IrBr(CO)2(κC-tBuImCH2PyCH2OMe)] being active. range aromatic primary...
Neutral and cationic cyclooctadiene rhodium(I) complexes with a lutidine-derived polydentate ligand having NHC methoxy side-donor functions, [RhBr(cod)(κC-tBuImCH2PyCH2OMe)] [Rh(cod)(κ2C,N-tBuImCH2PyCH2OMe)]PF6, have been prepared. Carbonylation of the compound yields dicarbonyl complex [Rh(CO)2(κ2C,N-tBuImCH2PyCH2OMe)]PF6 whereas carbonylation neutral affords mixture di- monocarbonyl [RhBr(CO)2(κC-tBuImCH2PyCH2OMe)] [RhBr(CO)(κ2C,N-tBuImCH2PyCH2OMe)]. These efficiently catalyze...
A series of rhodium and iridium complexes derived from lutidine-based ligands (lutidine, 2,6-dimethylpyridine) with NHC amino side-donor functions have been prepared characterized. Deprotonation the functionalized imidazolium salts, [tBuHImCH2PyCH2NR2]Br, by bridging methoxo dinuclear [M(μ-OMe)(cod)]2 affords [MBr(cod)(κC-tBuImCH2PyCH2NR2)] (M = Rh Ir) which a Rh(I) Ir(I) including [M(cod)(κ3C,N,N′-tBuImCH2PyCH2NR2)]+, [Rh(CO)(κ3C,N,N′-tBuImCH2PyCH2NR2)]+, [IrBr(CO)2(κC-tBuImCH2PyCH2NR2)]...
