A new ultramicroporous metal–organic framework with an anionic framework and counter cations accommodated in the large channels is reported for CO2 capture.
A smart H-phosphonate-mediated synthetic strategy for the sulfonylation of heteroaromatic N-oxides has been developed, by which a large variety of 2-sulfonyl quinolines/pyridines were synthesized starting from easily available sulfonyl chlorides, diisopropyl H-phosphonate and pyridine/quinoline N-oxides in one pot under metal-free conditions at room temperature.
A synthetic strategy for an iodine‐mediated sulfonylation of quinoline N‐oxides has been developed. A wide variety of 2‐sulfonyl quinoline derivatives were synthesized by reacting various quinoline N‐oxides with different sodium sulfinates in the presence of sub‐stoichiometric amounts of I2 in one pot, after 2 h at room temperature.
An efficient one-pot methodology for C2-selective amination and alkylation of quinoline N-oxides was developed in the presence of diethyl H-phosphonate.
A practical and efficient method for the synthesis of 2‐aroxy(alkoxy)quinolines has been developed by direct cross‐dehydrogenative coupling reaction between quinoline N‐oxides and readily available phenols and alcohols in the presence of H‐phosphonate and CCl4 under mild conditions.
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.
