Balamurugan, Gunasekaran; Balaji, Sundarraman; Ramesh, Rengan; Bhuvanesh, Nattamai S. P. published the artcile< Synthesis and Structures of Arene Ruthenium (II)-NHC Complexes: Efficient Catalytic α-alkylation of ketones via Hydrogen Auto Transfer Reaction>, Formula: C7H9NO, the main research area is arene ruthenium heterocyclic compound complex preparation; aryl alkyl ketone alkanol ruthenium catalyst chemoselective alkylation; alkyl aryl ketone preparation; hydroxymethyl aniline ketone ruthenium catalyst heterocyclization; quinoline preparation.
A panel of six new arene Ru (II)-NHC complexes (NHC = 1,3-diethyl-(5,6-dimethyl)benzimidazolin-2-ylidene, 1,3-dicyclohexylmethyl-(5,6-dimethyl)benzimidazolin-2-ylidene and 1,3-dibenzyl-(5,6-dimethyl)benzimidazolin-2-ylidene) were synthesized from the transmetallation reaction of Ag-NHC with [(η6-arene)RuCl2]2 and characterized. The ruthenium (II)-NHC complexes were developed as effective catalysts for α-alkylation of ketones and synthesis of bioactive quinoline using primary/amino alcs. as coupling partners resp. The reactions were performed with 0.5 mol% catalyst load in 8 h under aerobic condition and the maximum yield was up to 96%. Besides, the different alkyl wingtips on NHC and arene moieties were studied to differentiate the catalytic robustness of the complexes in the transformations.
Applied Organometallic Chemistry published new progress about Alkylation catalysts, regioselective. 5344-90-1 belongs to class alcohols-buliding-blocks, and the molecular formula is C7H9NO, Formula: C7H9NO.
