Abstract: An iron-catalyzed redox-neutral, decarboxylative olefination of cycloketone oxime esters with α,β-unsaturated carboxylic acids has been developed. This reaction involves an iminyl radical mediated C-C bond cleavage/radical addition/decarboxylation cascade. This protocol is highlighted by its low-cost… read more here.

Abstract: A novel sp3 C-SCF3 coupling reaction between cycloketone oxime esters and S-trifluoromethyl 4-methylbenzenesulfonothioate was achieved. Ethanol was found to facilitate this transformation by trapping the sulfonyl cation. The metal-free and photocatalyst-free reaction conditions, as well… read more here.

DOI: 10.1021/acscatal.9b02830
Abstract: A visible light-induced and exogenous photosensitizer-free, copper-catalyzed radical aminocarbonylation of cycloketone oxime esters with CO gas and amines is developed. The mild catalytic system involving CuCl and N,N,N-tridentate ligand shows good reactivity and chemoselectivity, and… read more here.
