Thermochemical excitation enabled efficient α-aryl malonates synthesis from 2-diazo-3-aryl ketoesters and alcohols under transition metal-free reaction conditions. Furthermore, an unusual C[sbnd]C bond cleavage and C[sbnd]O/(N) bond formation occurred whe

The Ritter reaction utilizing tert-butyl acetate as the tert-butyl cation source was investigated by in situ FTIR and calorimetry under various reaction conditions. It was established that, when a batch mode reaction in acetic acid was performed, minimal isobutylene was evolved into the headspace, thereby avoiding pressurization of the reaction vessel. The safety of these conditions is due to the equilibrium of isobutylene and acetic acid with tert-butyl acetate. In addition, the observation of acetic anhydride provided insight into the role of acetic acid in the mechanistic pathway.

The selective rearrangement of oxaziridines to amidesviaa single electron transfer (SET) pathway is unexplored. In this study, we present a weak base-promoted selective rearrangement of oxaziridines to amidesviavisible-light photoredox catalysis. The developed method shows excellent functional group tolerance with a broad substrate scope and good to excellent yields. Furthermore, control experiments and density functional theory (DFT) calculations are performed to gain insight into the reactivity and selectivity.
