Herein, we report the catalytic activity of a series platinum(II) pre-catalysts, bearing N-heterocyclic carbene (NHC) ligands, in alkene hydrosilylation reaction. Their structural and electronic properties are fully investigated using X-ray diffraction analysis nuclear magnetic resonance spectroscopy (NMR). Next, our study presents structure-activity relationship within this group pre-catalysts gives mechanistic insights into catalyst activation step. An exceptional performance one complexes...
Eight new dinuclear gold(I) complexes, [Au2(L)X2] (1–8), were synthesized using a straightforward synthetic procedure under very mild conditions. The complexes have been characterized by NMR spectroscopy, elemental analysis, and single-crystal X-ray structure analysis. Their catalytic activity was investigated in the carboxylative cyclization of propargylamine (PPA). A superior performance comparison to [Au(IPr)Cl] (9) obtained for 1 2 having an eight-methylene bridge connecting two NHCs...
Herein, we describe a straightforward access to chalcogenoureas derived from N-heterocyclic carbenes, and investigate the coordination chemistry of selenoureas with coinage metals.
In this report, we investigate the integration of a membrane separation protocol in line with gold-catalyzed hydration alkynes.
Abstract The integration of a membrane separation protocol with the platinum‐catalyzed hydrosilylation olefins is investigated. catalytic reaction first optimized in batch where [Pt(IPr*)(dms)Cl 2 ] (IPr*=1,3‐bis[2,6‐bis(diphenylmethyl)‐4‐methylphenyl]imidazol‐2‐ylidene, dms=dimethyl sulfide) demonstrates superior activity compared to less sterically encumbered [Pt(SIPr)(dms)Cl (SIPr=1,3‐bis(2,6‐diisopropylphenyl)imidazolidine) congener. Filtration conditions are identified screening...
A very simple Rh-based catalyst operates under heterogeneous flow conditions for the carbene transfer of methyl diazoacetate (MDA) with several substrates. Two different methods heterogenizing in a column reactor have been applied. Different X-H (X=O, S, Si, CH2 ) were successfully functionalized by and cyclopropenation was performed mild continuous conditions. Following these promising results, recycling experiments using both methodologies conducted which up to 5 catalytic cycles achieved...
Abstract BACKGROUND Transition metal catalysis has, over recent decades, developed into one of the most important methods constructing molecules. However, although efficient in construction complex molecules, these catalysts can be expensive as they are often based upon second‐ and third‐row transition metals which have, for part, low terrestrial abundance. Present removal recovery techniques homogeneous tend, at best, to focus on recovering center consider ligands single‐use components....
