Abstract: The development of different concept approaches and user-friendly carbonyl surrogates for aminocarbonylation is highly desirable. Herein, we report the photocatalytic aminocarbonylation of enaminones with easily available o-aminobenzamides and CF2Br2 through an oxygen migration-defluorination strategy. The… read more here.

DOI: 10.1039/d1nr03251h
Abstract: Combining density functional theory (DFT) calculations and ab initio molecular dynamics (AIMD) simulations, we show that oxygen functional groups exhibit unexpected spontaneous dynamic behaviors on the interior surface of single-walled carbon nanotubes (SWCNTs). The hydroxyl… read more here.
