I found the field of Chemistry very interesting. Saw the article Unexpected CNN-to-CC Ligand Rearrangement in Pincer-Ruthenium Precatalysts Leads to a Base-Free Catalyst for Ester Hydrogenation published in 2019. Category: benzofurans, Reprint Addresses Keith, JM; Chianese, AR (corresponding author), Colgate Univ, Dept Chem, 13 Oak Dr, Hamilton, NY 13346 USA.. The CAS is 87-41-2. Through research, I have a further understanding and discovery of Isobenzofuran-1(3H)-one

We report the conversion of a series of CNN-pincer-ruthenium complexes Ru(CNN)HCl(CO) to a CC-chelated form Ru(CC)(PR3)(2)H(CO) on reaction with sodium tert-butoxide and monodentate phosphines. When the phosphine is triphenylphosphine, 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 relationship in the series of CC-chelated complexes mirrors that in the precursor CNN-Ru complexes, potentially indicating a common catalytic mechanism. Density 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.
