Reaction of sulfurdiimines RN=S=NR and the isoelectronic and structurallyThe dimeric complexes [Me,Al{RNS(Me)X}] (X = 0, NR) exist in two conformations which undergo intramolecular interconversion in the case of the sulfurdiimine compounds, and probably also for the sulfinylaniline derivatives. In the latter case intermolecular exchange via a monometic species also plays a role. This monomer may be observed in dilute solutions. While the sulfinylaniline compounds are stable in solution (CDCI,, pyridine), the sulfurdiimine compounds decompose slowly in CDCL, and rapidly in pyridine to produce diazoaryls, some RNH, and polymeric products. The alcoholysis of the sulfurdiimine-Al complexes also usually give similar products_ The possible roles of nitrene N-R and radical RNS-Me intermediates in the decompositions are discussed.
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.
