A mechanism is proposed for the catalytic effect of the complexes, including ligand dissociation, oxidative attachment of the alcohol, and coordination of the ketone molecule with formation of an intermediate six-membered compound.doi:10.1007/BF01108177V. Z. Sharf...

Herein, we report a formal cross-electrophile coupling of carboxylic acids with aryl or alkyl halides enabled by photoredox and nickel catalysis, and phosphoranyl radical synergistic chemistry, leading to concise synthesis of ketones (Fig. 1b). Fig. 2: Proposed mechanism. Mechanistic proposal for ...

To gain insight into the mechanism of the reaction, we performed deuterium-labeling experiments. First, the reaction of 1ag was carried out in isopropanol-d8 to probe the keto–enol tautomerization of the substrate (Fig. 6a). In the absence of allylic alcohol, no H/D exchange at the α-...

Mechanism of action: Anin vitro studyin adipocytes showed that raspberry ketone increased theoxidationof fatty acids, inhibited lipid accumulation, and increased the secretion ofadiponectin(Park, 2010). At the molecular level,...
This initial work on administration of KBs from exogenous sources and their potential role in parenteral nutrition, primarily via intravenous infusion, informed the more recent development of ingestible ketone salts and ketone esters, now collectively referred to as exogenous ketone supplements (EKS). ...

stannylchlorides has also been reported. The high reactivity of the chlorine–tin bond is believed to be responsible for the activity of the reaction, assolvationinto a tightion paircould conceivably enhance the Lewis acidity of the tin center sufficiently to allow for a Type-I mechanism to ...
Its mechanism of action involves the modulation of the NF-κB signaling pathway, inhibition of the NLRP3 inflammasome, increasing antioxidant capacity, regulation of tight junction protein, and a potential to inhibit apoptosis and pyroptosis. Hence, BD-AcAc 2 KME emerges as a Author contributions ...
