The influence of substituent field and resonance effects on the ease of N-heterocyclic carbene formation from imidazolium rings
Using a set of twelve selected substituents, the influence of substituent properties on the ease of deprotonation of imidazolium cations and mesoionic imidazolium-4-olates measured by the CREF index has been investigated. Significant correlations between CREF values and the Swain and Lupton field (F...
