Zhao, Wei; Yan, Patrick K.; Radosevich, Alexander T. published the article 《A Phosphetane Catalyzes Deoxygenative Condensation of α-Keto Esters and Carboxylic Acids via PIII/PV=O Redox Cycling》. Keywords: phosphetane catalyst preparation oxygenative condensation ketoester carboxylic acid.They researched the compound: 4-Methyl-1-phenyl-2,3-dihydro-1H-phosphole 1-oxide( cas:707-61-9 ).COA of Formula: C11H13OP. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:707-61-9) here.
A small-ring phosphacycle is found to catalyze the deoxygenative condensation of α-keto esters and carboxylic acids. The reaction provides a chemoselective catalytic synthesis of α-acyloxy ester products with good functional group compatibility. Based on both stoichiometric and catalytic mechanistic experiments, the reaction is proposed to proceed via catalytic PIII/PV=O cycling. The importance of ring strain in the phosphacyclic catalyst is substantiated by an observed temperature-dependent product selectivity effect. The results point to an inherent distinction in design criteria for organophosphorus-based catalysts operating via PIII/PV=O redox cycling as opposed to Lewis base (nucleophilic) catalysis.
Although many compounds look similar to this compound(707-61-9)COA of Formula: C11H13OP, numerous studies have shown that this compound(SMILES:CC1=CP(CC1)(C2=CC=CC=C2)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
