Debbab, M.; Renault, S.; Eid, S.; Lozach, O.; Meijer, L.; Carreaux, F., Bazureau, J.P An efficient method for the preparation of new analogs of Leucettamine B under solvent-free microwave irradiation. The Japan Institute of Heterocyclic Chemistry(Heterocycles) 2009

A simple and efficient microwave-assisted protocol has been developed for the synthesis of new 2-amino-3,4-dihydro-4H-imidazol-4-one derivatives of leucettamine B. This solvent-free protocol involves sulphur/nitrogen displacement of 2-ethylthio-5-arylidene-imidazolone 5 with a variety of functionalized polar primary amines 6 and this general method afforded a small library of the desired pure products 7a-n in yields ranging from 33 to 92% in moderate reaction times (30-100 minutes).

Cp2Ti(dithiolene) and Cp2Ti(diselenolene) complexes containing the N-methyl-1,3-thiazoline-2-thione- 4,5-dithiolate ligand (Me-thiazdt), the N-phenyl-1,3-thiazoline-2-thione-4,5-dithiolate ligand (Ph-thiazdt) and the N-methyl-1,3-thiazoline-2-thione-4,5-diselenolate ligand (Me-thiazds) have been synthesized. Three approaches have been developed in order to generate the dithiolene or the diselenolene ligands which were reacted with Cp2TiCl2 to form the corresponding heteroleptic complexes. Their Xray crystal structures, UV–Vis absorption spectra as well as their redox properties, determined by cyclic voltammetry have been investigated and discussed. Variable-temperature 1H NMR experiments have been performed in order to determine the activation energies of the chelate ring inversion.

Eid, S.; Fourmigué, M.; Roisnel, T.; Lorcy, D. Influence of the Thiazole Backbone on the Structural, Redox, and Optical Properties of Dithiolene and Diselenolene Complexes ACS publications (Inorganic chemistry) 2007

Metalation of N-methyl-1,3-thiazoline-2-thione followed by reaction with elemental S or Se affords a simple and efficient approach to N-methyl-1,3-thiazoline-2-thione-4,5-dithiolate (Me-thiazdt) and the diselenolate (Me-thiazds) analogue. In the presence of metal II centers such as Zn, Ni, and Pd these ligands afford the corresponding dianionic dithiolene and diselenolene complexes. The Ni and Pd dianionic complexes are easily oxidized into the monoanionic species. Complexes were isolated and characterized by single-crystal X-ray crystallography. Most often a substitutional S/N-Me disorder is observed, attributable to the square-planar trans complexes disordered on two positions or coexistence of both cis and trans isomers on inversion centers. Monoanionic complexes exhibit a strong NIR absorption band with  values up to 33 750 M-1 cm-1.

Eid, S.; Guerro, M.; Roisnel, T.; Lorcy, D. Trithiaazafulvalene : A Promising Building Block between Tetrathiafulvalene and Dithiadiazafulvalene ACS publications (Organic letters) 2006

New electroactive building blocks, the trithiaazafulvalenes (TTAFs), were synthesized. These redox-active molecules, intermediate between tetrathiafulvalene (TTF) and dithiadiazafulvalene (DTDAF), show promising features for the elaboration of molecular materials.

Eid, S.; Guerro, M.; Lorcy, D. 1,3-Thiazoline-2-thione-4,5-dithiolato, an efficient building block towards functionalized dithiadiazafulvalenes Elsevier (Tetrahedron Letters) 2006

The first synthesis and X-ray structural determination of the bis(tetraethylammonium) Zn dithiolene complex involving N-methyl-1,3-thiazoline-2-thione-4,5-dithiolate, [NEt4]2[Zn(Me-thiazdt)2], are reported. The reactivity of this dithiolene complex as a nucleophilic dithiolate synthon and as a precursor of the air sensitive electron rich olefine, the bis ethylenedithiodithiadiazafulvalene (BEDT–DTDAF), is also described.
