Natural esterases hydrolyze esters under physiological pHs but chemists often have to use strongly acidic or basic conditions for the same hydrolysis. We report synthetic nanoparticle catalysts that hydrolyze nonactivated alkyl esters at ro...
Selective C-H Activation of Unprotected Allylamines by Control of Catalyst Speciation [0.03%]
通过控制催化剂的物种实现未保护亚胺茋衍生物的C-H键活化

Shih-Chieh Kao et al.
Ligand-to-metal charge transfer (LMCT) using stoichiometric copper salts has recently been shown to permit decarboxylative C-N bond formation via an LMCT/radical polar crossover (RPC) mechanism; however, this method is unable to function ca...
