The intermolecular C–C, C–O, C–S and C–N bonds construction between diazo compounds and acyclic, cyclic 1,3-dicarbonyl compounds, thiophenol, alkynes were developed by using a TFMSA@SBA-15, providing a metal-free and eco-friendly platform.
More economically and greener surface modified sewage sludge for carbene insertion of diazo compounds into O–H bond of phenols with good yields and high functional group tolerance.
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.
