چکیده
A family of anionic, formally nickel(0) complexes supported by bidentate NHC–pyridone ligands is described. The unsymmetric chelating environment and capping [K(18-crown-6)]+ countercation allow isolation single-component, monometallic in high yield. steric electronic properties are assessed through a battery experimental (NMR, IR, UV–vis, X-ray diffraction) computational tools. Catalytic activity for highly branched-selective hydroboration styrene with HBpin demonstrated. Control experiments implicate an important role the pyridone establishing reactivity regioselectivity, suggesting potential to leverage secondary coordination sphere effects these single-component precatalysts reagent activation delivery.

A family of well-defined Fe(II) complexes of the type {BnN(N-CH2(CH2)n-N'-tert-butyl-imidazole-2-ylidene)2}FeCl2 (Bn = benzyl; n = 1 (1) or 2 (2)), {BnN(N-CH2(CH2)n-N'-methylbenzimidazole-2-ylidene)2}FeCl2 (n = 1 (3) or 2 (4)) and {BnN(N-CH2CH2CH2-N'-methylbenzimidazole-2-ylidene)2}FeBr2 (5) has been synthesized. These complexes are rare examples of Fe species supported by bidentate NHC ligands...
متن کاملfac−Re(I)(tricarbonyl) complexes with anionic bidentate ligands
Investigation of the photophysical and photochemical properties of d transition metals, e.g. Ru(II), Re(I) or Os(II), complexes with heteroaromatic diimine ligands (N∩N) is one of the main topics of modern inorganic physical chemistry. In general, the excited state behaviour of such compounds is governed by the interplay between the metal-to-ligand (MLCT) charge-transfer and intra-ligand excite...
متن کاملSynthesis, structure and reactivity of Pd and Ir complexes based on new lutidine-derived NHC/phosphine mixed pincer ligands.
Coordination studies of new lutidine-derived hybrid NHC/phosphine ligands (CNP) to Pd and Ir have been performed. Treatment of the square-planar [Pd(CNP)Cl](AgCl2) complex 2a with KHMDS produces the selective deprotonation at the CH2P arm of the pincer to yield the pyridine-dearomatised complex 3a. A series of cationic [Ir(CNP)(cod)]+ complexes 4 has been prepared by reaction of the imidazolium...

متن کاملBidentate Isatin Schiff Base Ligands Oxovanadium (IV) Complexes
The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.
