of ketone silyl enol ethers with diazomethyl‐substituted hypervalent iodine reagents that gives access to unusual β‐diazocarbonyl compounds. The potential of this unexplored class of diazo compounds for the development of new reactions was demonstrated by the discovery of a rare Rh‐catalyzed intramolecular 1,3 C−H carbene insertion that led to complex cyclopropanes with excellent stereocontrol.

agrochemical applications. In this study, we present a visible light-mediated photoredox neutral strategy for the fluoroalkylation of tertiary alkyl chlorides under transition-metal-free conditions. This method allows for the facile synthesis of fluoroalkylated all-carbon quaternary centers, exhibiting excellent functional group compatibility. Mechanistic studies reveal the involvement of two reactive

Synthesis and in vitro evaluation of donepezil-based reactivators and analogues for nerve agent-inhibited human acetylcholinesterase
Donepezil-based reactivators 1–3 show a better ability (8 fold higher) than pralidoxime to reactivate VX-hAChE, and oxime 2 is 5 to 11 fold more efficient than pralidoxime and HI-6 respectively to reactivate of VX-hBChE.
