Mechanism of the oxidative addition of aryl halides to bis-carbene palladium(0) complexes*
Bis-N-heterocyclic carbenes Pd0 complexes, Pd(NHC)2, are efficient catalysts in Heck reactions performed with aryl bromides or chlorides. The Pd(NHC)2 that are not stable are generated in situ from PdII precursors PdY2(NHC)2 (Y = halides) after a chemical reduction. The latter procedure can be mimicked by an electrochemical reduction. The transient Pd(NHCBn)2 is generated by electrochemical red...
متن کاملSynthesis and reactivity of alkyl-palladium N-heterocyclic carbene complexes.
The transamination of alkyl-palladium halide N-heterocyclic carbene complexes has enabled the isolation of products that reveal interesting insights into the factors which might be barriers to the development of a palladium-catalysed alkyl-amination reaction.
متن کاملOxidative addition of aryl chlorides to palladium N-heterocyclic carbene complexes and their role in catalytic arylamination
Density functional theory has been used to investigate various solvated species that may be formed from palladium bis N-heterocyclic carbene complexes, [Pd(cyclo-C{NRCH}2)2], (PdL2) in benzene solution. Formation of an g -arene complex is shown to stabilise a monocarbene species, PdL(g-C6H5X), where the arene is either the solvent or a reacting aryl halide. Oxidative addition of an aryl chlorid...

متن کاملSynthesis and reactivity of triethylborane adduct of N-heterocyclic carbene: versatile synthons for synthesis of N-heterocyclic carbene complexes.
The reaction of an imidazolium salt with LiBEt(3)H afforded triethylborane adduct of imidazol-2-ylidene, which can act as a carbene precursor for the synthesis of a transition metal complex as well as a main group element complex.
