A Highly Efficient Gold‐Catalyzed Oxidative CC Coupling from CH Bonds Using Air as Oxidant

Understanding the synergistic effects of gold bimetallic catalysts

“…Supported gold NPs have shown promising catalytic performance for a variety of reactions, including propene oxidation [2], the water gas shift reaction [3], selective oxidation of alcohols [4], and selective hydrogenation of unsaturated aldehydes [5,6], among others [7]. The performance of gold NPs is highly dependent on the particle size, the nature of the support, and the preparation procedure, and the effects of these factors can be understood based on different active site models, such as low-coordinated gold atoms [8,9], the perimeter interface between gold and the support [10][11][12], and charged gold species [13][14][15].…”

Visible‐Light‐Promoted Asymmetric Cross‐Dehydrogenative Coupling of Tertiary Amines to Ketones by Synergistic Multiple Catalysis

“…[1][2][3][4] Thed evelopment of catalytic enantioselective versions has since been actively pursued to include the asymmetric a-coupling of carbonyls,t hus adding new variants to the fundamental a-carbonyl chemistry.D espite the advances,t he successes with simple aldehydes and ketones have been rather limited.

Highly efficient heterogeneous aerobic cross-dehydrogenative coupling via C–H functionalization of tertiary amines using a nanoporous gold skeleton catalyst

“…Other oxidants, such as mchloroperoxybenzoic acid (mCPBA) and di-tert-butyl peroxide (DTBP) exhibited poor activities and H2O2 resulted in a very low yield of 3a due to its rapid decomposition by AuNPore. (entries [10][11][12]. Thus, two optimal conditions, method A (O2 at 80 o C, entry 1) and method B (TBHP in decane at rt, entry 9) were used for further studying the substrate scope.…”
