pK(a) values of 19.8-28.2 are reported for the conjugate acids of a large series of NHCs in water. The effects of ring size, N-substituent and C(4)-C(5) saturation on pK(a) are discussed. 
An Acidity Scale of Triazolium-Based NHC Precursors in DMSO.
TLDR
An acidity scale of triazolium-based N-heterocyclic carbene precursors was established by measuring 25 compounds' equilibrium acidities in dimethyl sulfoxide (DMSO) solution using overlapping indicator method, responding not only to the N-aryl motif, but also to the core structure. Expand

Targeted and Systematic Approach to the Study of pKa Values of Imidazolium Salts in Dimethyl Sulfoxide.
TLDR
Through the systematic change in the structure of the imidazolium cation, the effect of varying substituents at each position on the heterocyclic ring was determined; particularly, the transmission of electronic effects was quantified using Hammett parameters. Expand
Ln(II) amido complexes coordinated by ring-expanded N-heterocyclic carbenes - promising catalysts for olefin hydrophosphination.

A catalytic intramolecular nitrene insertion into a copper(i)-N-heterocyclic carbene bond yielding fused nitrogen heterocycles.
TLDR
N-(2-Azidophenyl)azolium salts were easily prepared and reacted with copper(i) under conditions allowing the formation of NHC complexes, and this reaction is proposed to proceed via dinitrogen elimination and imido/nitrene-NHC cyclization. Expand
A Cooperative N-Heterocyclic Carbene/Palladium Catalysis System.
TLDR

Organocatalysis by N-heterocyclic carbenes.
TLDR
The inversion of the classical reactivity (Umpolung) opens up new synthetic pathways in biochemical processes as nucleophilic acylations and in nature, the coenzyme thiamine (vitamin B1), a natural thiazolium salt, utilizes a catalytic variant of this concept in biochemical process as nucleophile acylation.

Formation and stability of N-heterocyclic carbenes in water: the carbon acid pKa of imidazolium cations in aqueous solution.
TLDR
Evidence is presented that the reverse protonation of imidazol-2-yl carbenes by solvent water is limited by solvent reorganization and occurs with a rate constant of kHOH = kreorg = 10(11) s-1, and a simple rationale for the observed substituent effects on the thermodynamic stability of N-heterocyclicCarbenes is presented.
