Transition metal mediated formation of dicationic diselenides stabilised by N-heterocyclic carbenes: designed synthesis.
Reactions of the N-heterocyclic carbene derivatives of selenium(ii) dihalides, LSeX2 (X = Cl, Br; L = 1,3-dibutylbenzimidazol-2-ylidene, C15H22N2) (4b, 4b'), L'SeX2 (X = Cl, Br; L' = 1,3-di(n)propylbenzimidazol-2-ylidene, C13H18N2) (4c, 4c') and L''SeX2 (X = Cl, Br; L'' = 1,3-di(i)propylbenzimidazol-2-ylidene, C13H18N2) (4d, 4d') with iron led to the formation of dicationic diselenides, [L2Se2(...
متن کاملDiverse chemical applications of N-heterocyclic carbenes.
N-Heterocyclic carbenes, or NHCs as they are commonly abbreviated, have attracted significant interest over the past decade due to their widespread utility in chemical transformations. As ligands on transition metals, NHCs have been found to have properties similar to those of the widely employed phosphine ligand, due to their ability to act as both a Lewis base and a Lewis acid at the same tim...
متن کاملFacile synthesis of metal N-heterocyclic carbene complexes.
A novel electrochemical procedure for the preparation of metal complexes of N-heterocyclic carbenes using imidazolium salts or corresponding silver-NHC complexes as carbene sources and electrolytes, and metal plates as the sacrificial anodes is described. The procedure is simple and good yielding without the use of expensive or air-sensitive reagents.
متن کاملMetal free catalytic hydroboration of multiple bonds in methanol using N-heterocyclic carbenes under open atmosphere.
An easy to operate method of catalytic hydroboration of unsaturated compounds has been developed with wide substrate scope. Reactions of various aldimines, ketimines, α,β-unsaturated carbonyl compounds, and alkynes were successfully executed with bis(pinacolato)diboron and N-heterocyclic carbenes in methanol without requiring a transition metal or inert atmosphere.
متن کاملPalladium(II) complexes based on 1,8-naphthyridine functionalized N-heterocyclic carbenes (NHC) and their catalytic activity.
Palladium complexes containing 2,7-bis(mesitylimidazolylidenyl)naphthyridine (NHC-NP) have been synthesized and characterized. Reaction of [{Ag(3)(NHC-NP)(2)}(PF(6))(3)] with [Pd(PhCN)(2)Cl(2)] provided an unusual dipalladium complex bridged by two NHC-NP units, forming a 20-membered dinuclear metallacycle [{Pd(2)(NHC-NP)(2)Cl(2)}(PF(6))] (2) in high yield. Treatment of 2 with KI in acetone yie...
