Asian Journal of Organic Chemistry, EarlyView.High‐valent Rh(IV) and Rh(V) species have been invoked to rationalize enhanced catalytic reactivity. This review examines evidence for both, emphasizing reactions proceeding through the Rh(III)/Rh(IV)/Rh(II) cycle. While Rh(V) intermediates are computationally supported, experimental evidence is limited; Rh(IV) species are supported by both theory and ...

Dynamic Kinetic Resolution of Hetero biaryl Ketones by Zinc- Catalyzed Asymmetr ic Hydrosil ylation [PDF]
, 2019 Adiastereo- and highly enantioselective dynamic kinetic resolution (DKR) of configurationally labile hetero- biaryl ketones is described. The DKR proceeds by zinc- catalyze dhydrosilylation of the carbonyl group ,thus leading to ...

Activation of Rac-1 and RhoA contributes to podocyte injury in chronic kidney disease [PDF]
, 2013 Rho-family GTPases like RhoA and Rac-1 are potent regulators of cellular signaling that control gene expression, migration and inflammation. Activation of Rho-GTPases has been linked to podocyte dysfunction, a feature of chronic kidney diseases (CKD). We

Electrolyte‐Controlled Regiodivergent Continuous Flow Electroselenocyclisations
Angewandte Chemie International Edition, EarlyView.A single‐pass, continuous‐flow electrolysis strategy – finely tuned by electrolyte choice – unlocks regiodivergent electroselenocyclisations of diselenides and oximes. By selectively guiding radical or ionic pathways through controlled substrate activation, this method enables a sustainable and highly selective synthesis of seleno‐functionalised ...

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates
ChemCatChem, EarlyView.The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Expedient, Directed Ir‐Catalyzed Diborylation of (Hetero)Biaryls via a Tridentate Ligand
ChemCatChem, EarlyView.The iridium‐catalyzed diborylation of 2‐aryl pyridines and isoquinolines with B2pin2 is reported. Using [Ir(OMe)(COD)]2 and a terpyridine derivative as a tridentate ligand, the heterobiaryls were selectively diborylated at the 2,6‐positions of the carbocycle.
