p-Nitroaryl)diarylmethanes are readily prepared via vicarious nucleophilic substitution of hydrogen in nitroarenes with carbanions of diarylmethyl p-chlorophenyl sulfide. These carbanions are efficient reagents for introduction of diarylmethyl substituents in the para position of nitroarenes via the VNS reaction. The reaction does not proceed ortho to the nitro group due to steric hindrances on the addition step.
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.
