Described here is a synthetic approach to access two of the most widely invoked cationic cobaltacycles in Cp*CoIII -catalyzed C-H functionalization reactions by C-H activation. The unique stabilizing capability of MeCN was used to surmount the previo

A case study in the (re)discovery of a non-diazo, catalytic, electrophilic cyclopropanation reaction is presented to illustrate the role of mechanistic concepts in chemical innovation. The specific instance also highlights how specific personalities

Chloromethylgold(I) complexes of phosphine, phosphite, and N‐heterocyclic carbene ligands are easily synthesized by reaction of trimethylsilyldiazomethane with the corresponding gold chloride precursors. Activation of these gold(I) carbenoids with

Methylenation of electron-rich olefins is a highly challenging reaction, for which we have developed a new methodology exploiting Pd-catalysis and halomethylboronate reagents, the latter replacing diazomethane and zinc carbenoids as methylene donors.

Straightforward deprotonation of soluble tetramethylammonium salts with alkyllithium reagents gives lithiomethyl trimethylammonium reagents. Coordination of the Li cation is crucial to the stability of these ‘N–C ylides’. These reagents were us

Lithiomethyl trimethylammonium triflate, prepared from tetramethylammonium triflate, cyclopropanates several styrenes and stilbenes with electron-donating and selected electron-withdrawing substituents efficiently. Kinetic data support a stepwise nuc
