Abstract
A series of ruthenium complexes (Ru1-Ru4) bearing new NNN-pincer ligands were synthesized in 58-78% yields. All of the complexes are air and moisture stable and were characterized by IR, NMR, and high-resolution mass spectra (HRMS). In addition, the structures of Ru1-Ru3 were confirmed by X-ray crystallographic analysis. These Ru(II) complexes exhibited high catalytic efficiency and broad functional group tolerance in the N-methylation reaction of amines using CH3OH as both the C1 source and solvent. Experimental results indicated that the electronic effect of the substituents on the ligands considerably affects the catalytic reactivity of the complexes in which Ru3 bearing an electron-donating OMe group showed the highest activity. Deuterium labeling and control experiments suggested that the dehydrogenation of methanol to generate ruthenium hydride species was the rate-determining step in the reaction. Furthermore, this protocol also provided a ready approach to versatile trideuterated N-methylamines under mild conditions using CD3OD as a deuterated methylating agent.

Abstract
Neutral and cationic cyclooctadiene rhodium(I) complexes with a lutidine-derived polydentate ligand having NHC and methoxy side-donor functions, [RhBr(cod)(κC-tBuImCH2PyCH2OMe)] and [Rh(cod)(κ2C,N-tBuImCH2PyCH2OMe)]PF6, have been prepared. Carbonylation of the cationic compound yields the dicarbonyl complex [Rh(CO)2(κ2C,N-tBuImCH2PyCH2OMe)]PF6 whereas carbonylation of the neutral compound affords a mixture of di- and monocarbonyl neutral complexes [RhBr(CO)2(κC-tBuImCH2PyCH2OMe)] and [RhBr(CO)(κ2C,N-tBuImCH2PyCH2OMe)]. These complexes efficiently catalyze the hydrosilylation of 1-hexyne with HSiMe2Ph with a marked selectivity towards the β-(Z)-vinylsilane product. Catalyst [RhBr(CO)(κ2C,N-tBuImCH2PyCH2OMe)] showed a superior catalytic performance, in terms of both activity and selectivity, and has been applied to the hydrosilylation of a range of 1-alkynes and phenylacetylene derivatives with diverse hydrosilanes, including HSiMe2Ph, HSiMePh2, HSiPh3 and HSiEt3, showing excellent β-(Z) selectivity for the hydrosilylation of linear aliphatic 1-alkynes. Hydrosilylation of internal alkynes, such as diphenylacetylene and 1-phenyl-1-propyne, selectively affords the syn-addition vinylsilane products. The β-(Z) selectivity of these catalysts contrasts with that of related rhodium(I) catalysts based on 2-picolyl-functionalised NHC ligands, which were reported to be β-(E) selective. An energy barrier ΔG‡ of 19.8 ± 2.0 kcal mol-1 (298 K) has been determined from kinetic studies on the hydrosilylation of 1-hexyne with HSiMe2Ph. DFT studies suggest that the methoxy-methyl group is unlikely to be involved in the activation of hydrosilane, and then hydrosilane activation is likely to proceed via a classical Si-H oxidative addition.

Abstract
![]()
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 by 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)]n is
a linear coordination polymer formed by bimetallic [Cu(μ-Br)]2 units linked by the lutidine-based NHC-py-NEt2 ligand, which acts as a heteroditopic ligand with a 1κC-2κ2N,N′ coordination
mode. We propose that the polymeric compounds break down in the solution
into more compact tetranuclear [Cu2(μ-Br)2(tBuImCH2pyCH2L)]2 compounds
with a coordination mode identical to the functionalized NHC ligands.
These compounds have been found to exhibit high catalytic activity
in the Cu-catalyzed azide–alkyne cycloaddition (CuAAC) reaction.
In particular, [Cu2(μ-Br)2(tBuImCH2pyCH2NEt2)]2 efficiently
catalyzes the click reaction of a range of azides and alkynes, under
an inert atmosphere at room temperature in neat conditions at a very
low catalyst loading, to quantitatively afford the corresponding 1,4-disubstituted
1,2,3-triazole derivatives in a few minutes. The cycloaddition reaction
of benzyl azide to phenylacetylene can be performed at 25–50
ppm catalyst loading by increasing the reaction time and/or temperature.
Reactivity studies have shown that the activation of the polynuclear
catalyst precursor involves the alkyne deprotonation by the NHC moiety
of the polydentate ligand to afford a copper(I)-alkynyl species bearing
a functionalized imidazolium ligand. DFT calculations support the
participation of the dinuclear species [(CuBr)2(μ-tBuImCH2pyCH2NEt2)], resulting
from the fragmentation of the tetranuclear compound, as the catalytically
active species. The proposed reaction pathway proceeds through zwitterionic
dinuclear intermediates and entails the active participation of both
copper atoms, as well as the NHC moiety as an internal base, which
activates the reacting alkyne via deprotonation.

Abstract
N-methylated amines are essential bioactive compounds and have been widely used in the fine and bulk chemical industries, as well as in pharmaceuticals, agrochemicals, and dyes. Developing green, efficient, and low-cost catalysts for methylation of amines by using efficient and easily accessible methylating reagents is highly desired yet remains a significant challenge. Herein, we report the selective N-dimethylation of different functional amines with different functional aldehydes under easy-to-handle and industrially applicable conditions using carbon-supported Ru nanoparticles (Ru/C) as a heterogeneous catalyst. A broad spectrum of amines could be efficiently converted to their corresponding N,N-dimethyl amines with good compatibility of various functional groups. This method is widely applicable to N-dimethylation of primary amines including aromatic, aliphatic amines with formaldehyde, and synthesis of tertiary amines from primary, secondary amines with different functional aldehydes. The advantage of this newly described method includes operational simplicity, high turnover number, the ready availability of the catalyst, and good functional group compatibility. This Ru/C catalyzed N-dimethylation reaction possibly proceeds through a two-step N-methylation reaction process.
