Single-electron N-heterocyclic carbene (NHC) catalysis has gained attention recently for the synthesis of C-C bonds. Guided by d. functional theory and mechanistic analyses, authors report the light-driven synthesis of aliphatic and α-amino ketones using single-electron NHC operators. Computational and exptl. results reveal that the reactivity of the key radical intermediate is substrate-dependent and can be modulated through steric and electronic parameters of the NHC. Catalyst potential is harnessed in the visible-light driven generation of an acyl azolium radical species that underwent selective coupling with various radical partners to afford diverse ketone products. This methodol. is showcased in the direct late-stage functionalization of amino acids and pharmaceutical compounds, highlighting the utility of single-electron NHC operators. In the experiment, the researchers used many compounds, for example, Di(1H-imidazol-1-yl)methanone(cas: 530-62-1HPLC of Formula: 530-62-1)
Di(1H-imidazol-1-yl)methanone(cas: 530-62-1) is a peptide coupling reagent,it is used in the synthesis of peptides. Reacts readily with carboxylic acids to form acyl imidazoles; subsequent reaction with amines to form amides goes smoothly.HPLC of Formula: 530-62-1
