Reference of 2213-63-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 2213-63-0, 2,3-Dichloroquinoxaline, introducing its new discovery.
Synthesis and Reactivity of a Bio-inspired Dithiolene Ligand and its Mo Oxo Complex
An original synthesis of the fused pyranoquinoxaline dithiolene ligand qpdt2- is discussed in detail. The most intriguing step is the introduction of the dithiolene moiety by Pd-catalyzed carbon-sulfur coupling. The corresponding MoIVO complex (Bu4N)2[MoO(qpdt)2] (2) underwent reversible protonation in a strongly acidic medium and remained stable under anaerobic conditions. Besides, 2 was found to be very sensitive towards oxygen, as upon oxidation it formed a planar dithiin derivative. Moreover, the qpdt2- ligand in the presence of [MoCl4(tBuNC)2] formed a tetracyclic structure. The products resulting from the unique reactivity of qpdt2- were characterized by X-ray diffraction, mass spectrometry, NMR spectroscopy, UV/Vis spectroscopy, and electrochemistry. Plausible mechanisms for the formation of these products are also proposed. Molybdopterin mimic: The synthesis of bio-inspired fused pyranoquinoxaline dithiolene ligand qpdt2- is discussed in detail. The most important step was introduction of the dithiolene moiety by Pd-catalyzed carbon-sulfur coupling. Reactions of MoIVO complex (Bu4N)2[MoO(qpdt)2], which mimics the active site of Mo enzymes, with protons, oxygen, and isocyanides led to new reactions and products (see scheme).
