TLDR
In this article, an improved synthesis of the title compounds was reported, and the N,N'-dialkylthioureas 1 with 3-hydroxy-2-butanone gave the imidazole-2(3H)-thiones 2 which on treatment with potassium in boiling tetrahydrofuran give the IMidazol-2ylidenes 3 in excellent yieldsAbstract:

Synthesis and Characterization of the Germathioacid Chloride Coordinated by an N-Heterocyclic Carbene §
TL;DR: In this article, the authors used N-heterocyclic carbene (Im-i-Pr2Me2) to synthesize a carboxylic acid chloride with germanium-sulfur bond.
Mechanism and kinetics of homogeneous catalysis
TL;DR: Xiong et al. as mentioned in this paper employed a model-based approach using a diverse set of data including monomer consumption, evolution of molecular weight, and end-group analysis to determine each of the reaction specific rate consta nt involved in 1-hexene polymerization catalyzed by a family of group IV single-site catal ysts.
