Nandi, Jyoti published the artcileCombining Oxoammonium Cation Mediated Oxidation and Photoredox Catalysis for the Conversion of Aldehydes into Nitriles, Related Products of piperidines, the publication is Synlett (2018), 29(16), 2185-2190, database is CAplus.
A method to oxidize aromatic aldehydes to nitriles has been developed. It involves a dual catalytic system of 4-acetamido-TEMPO and visible-light photoredox catalysis. The reaction is performed using ammonium persulfate as both the terminal oxidant and nitrogen source.
Synlett published new progress about 219543-09-6. 219543-09-6 belongs to piperidines, auxiliary class Piperidine,Fluoride,Salt,Amine,Amide, name is 4-Acetamido-2,2,6,6-tetramethyl-1-oxopiperidinium Tetrafluoroborate, and the molecular formula is C11H21BF4N2O2, Related Products of piperidines.
