Issue: Chem - Cell

In the February issue of Cell Reports Physical Science, Melen and co-workers report the reactivity of diaryl-substituted esters with R 3 P/B(C 6 F 5) 3 frustrated Lewis pairs (FLPs). Although ester C–O activation occurs for all FLP systems, the use of Mes 3 P induces single-electron transfer to generate a [Mes 3 P] ·+ /[C(H)Ar 2] · radical ion pair. In the presence of olefins, this ...

Abstract. Intermolecular cycloaddition of tosylhydrazones with nitriles was investigated. t-BuOK was shown to be an excellent base for increasing the effectiveness of the reaction in this protocol, and homocoupling of the tosylhydrazones was significantly inhibited by using xylene as a solvent.Through this transformation, a variety of 4,5-diaryl-2 H-1,2,3-triazoles were prepared in good to ...
