Abstract: Herein, we report a water-accelerated, N -heterocyclic carbene (NHC)-catalyzed aza-Michael addition reaction to access β-aminosulfonyl fluorides, which are key hubs of the sulfur(VI) fluoride exchange (SuFEx) reaction. As a crucial reaction medium, water considerably enhances… read more here.

DOI: 10.1021/acscatal.2c05573
Abstract: Water is ubiquitous in olefin metathesis, at levels ranging from contaminant to cosolvent. It is also non-benign. Water-promoted catalyst decomposition competes with metathesis, even for “robust” ruthenium catalysts. Metathesis is hence typically noncatalytic for demanding… read more here.

DOI: 10.1038/s41467-020-19405-5
Abstract: Previous studies have shown that copolymer compositions can significantly impact self-healing properties. This was accomplished by enhancement of van der Waals (vdW) forces which facilitate self-healing in relatively narrow copolymer compositional range. In this work… read more here.
