A N-aryloxide-amidine ligand (H3L), integrating phenoxide (PhO-) and amidine ligands through methylene linkers, has been synthesized from 2-(aminomethyl)-6-(tert-butyl)phenol in two steps. Upon reacting the deprotonated H3L ligand with group 4...
Organophosphorus compounds (OPCs) have wide application in organic synthesis, material sciences, and drug discovery. Generally, the vast majority of phosphorus atoms in OPCs are derived from white phosphorus (P 4 ). However, the large-scale preparation of OPCs mainly proceeds through the multistep and environmentally toxic chlorine route from P 4 . Herein, we report the direct benzylation of P 4 promoted by visible light. The cheap and readily available benzyl bromide was used as a benzylation reagent, and tetrabenzylphosphonium bromide was directly synthesized from P 4 . In addition, the metallaphotoredox catalysis strategy was applied to functionalize P 4 for the first time, which significantly improved the application range of the substituted benzyl bromide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
