Le, Linh published the artcileUnexpected CNN-to-CC Ligand Rearrangement in Pincer-Ruthenium Precatalysts Leads to a Base-Free Catalyst for Ester Hydrogenation, Formula: C11H22O2, the main research area is bidentate pyridylbenzimidazolylidene ruthenacycle preparation catalyst ester hydrogenation; crystal structure bidentate pyridylbenzimidazolylidene ruthenacycle; mol structure bidentate pyridylbenzimidazolylidene ruthenacycle.
The authors report the conversion of CNN-pincer-Ru complexes Ru(CNN)HCl(CO) to a CC-chelated form Ru(CC)(PR3)2H(CO) on reaction with Na tert-butoxide and monodentate phosphines. When the phosphine is PPh3, cis-phosphine complexes form at room temperature, which convert to the trans isomer at elevated temperatures When the phosphine is tricyclohexylphosphine, only the trans-phosphine isomer is observed The CC-chelated complexes are active catalysts for the hydrogenation of esters, without the need for added base. The ligand structure-activity relation in CC-chelated complexes mirrors that in the precursor CNN-Ru complexes, potentially indicating a common catalytic mechanism. D. functional theory calculations establish a plausible mechanism for the CNN-to-CC rearrangement and demonstrate that this rearrangement is potentially reversible under the conditions of ester hydrogenation catalysis.
