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:

Amino acid derivatives and pharmaceutical uses thereof
TL;DR: In this paper, novel Amino acid derivatives and pharmaceutical uses are presented. But the use of transglutaminase has not yet been discussed, except in the context of immunosuppressive drugs.
Journal ArticleDOI
N-heterocyclic carbene and cyclic (alkyl)(amino)carbene adducts of plumbanes and plumbylenes.
TL;DR: In this paper , the NHC-containing plumbane adducts with PbI2 and PbCl2Ph2 were shown to be stable in the solid state but decompose in solution.
Journal ArticleDOI
Carbene-mediated synthesis of a germanium tris(dithiolene)dianion.
TL;DR: In this paper, the structure and bonding of tris(dithiolene) complexes of main-group elements were probed by experimental and theoretical methods, and it was suggested that carbene-mediated partial hydrolysis may represent a new method to access tris-dithioene complexes.

Coordination of N-heterocyclic carbene to Si–Si and P–P multiple bonded compounds
TL;DR: In this article, the coordination chemistry of N-heterocyclic carbene (NHC) to silicon-silicon and phosphorus-phosphorus multiple-bond motifs is discussed.
