A cyclic (alkyl)(amido)carbene: synthesis, study and utility as a desulfurization reagent

The synthesis and study of a cyclic (alkyl)(amido) carbene is described. The carbene was found to undergo C-H insertion at low temperatures, formed cyclopropenes upon exposure to alkynes, and facilitated desulfurization reactions. Spectroscopic studies revealed that the carbene is strongly pi-accepting but retains a complimentary degree of sigma-donating properties.
