In this review, we summarize the chemistry of water compatible supramolecular polymers (WCSPs) based on the core supramolecular approaches at play, namely hydrogen-bonding arrays, electrostatic interactions, large π-conjugated subunits, host–guest interactions, and peptide-based systems, respectively. We discuss both synthesis and polymer structure, as well as the underlying design expectations and potential applications.

Copper-mediated direct S-N formation using readily available starting materials via an oxygen-activated radical process has been developed. This method provides a novel and direct approach for synthesis of sulfonamides under air conditions.

A highly efficient amidation reaction of heterocycles with N-fluorobenzenesulfonimide (NFSI) has been developed, presumably proceeding via C-H bond activation. Cuprous iodide was employed as the catalyst, and various α-amidated heterocycle derivatives have been generated in good to excellent yields. This chemistry endowed an economic method of synthesis of valuable amidated heterocycles through a direct C-N bond-coupling processes.
