Reactivity of an Unprotected Mesoionic <i>N</i>-Heterocyclic Olefin
Qiuming Liang, Kasumi Hayashi, Datong Song
Abstract
We report a novel mesoionic N-heterocyclic olefin (mNHO) derived from a 1,2,3-triazolium salt. With the carbenic position unprotected, the mNHO can tautomerize into the mesoionic carbene (MIC) form at room temperature. The reactivity of this new mNHO with various group 13 Lewis acids and CO2 have been studied experimentally and computationally.
