Intermolecular alkyl/aryl exchange of 2-iminothiazoles with isothiocyanates and isocyanates: scopes and limitations was written by Shin, Dongyun;Lee, Jihoon;Hahn, Hoh-Gyu. And the article was included in Tetrahedron in 2010.Product Details of 2740-88-7 This article mentions the following:
2-Iminothiazole, an isoform of 2-aminothiazole, is a scaffold of synthetic and medicinal significance. An efficient method by which alkyl group attached to the imine nitrogen of 2-alkyliminothiazoles is changed into other alkyl groups by isothiocyanates is reported. All the reactions were carried out in toluene at 105° without any additive. The reaction is a reversible process and the equilibrium is determined by the reactivity of both reactants, in which the more electron-withdrawing alkyl or aryl groups at the 2-imino group or isothiocyanate showed higher reactivities. A synthetic problem in 2-iminothiazole chem., synthesis of amino acid-derived 2-iminothiazole was solved in a very simple manner. Using suitably designed 2-iminothiazole substrate, the electrophilic reactivity of various isothiocyanates could be empirically compared by this exchange reaction. Moreover, successful exchange reaction using isocyanates instead of isothiocyanates broadened the utility of this reaction. In the experiment, the researchers used many compounds, for example, 4-Fluorobenzylisothiocyanate (cas: 2740-88-7Product Details of 2740-88-7).
4-Fluorobenzylisothiocyanate (cas: 2740-88-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Product Details of 2740-88-7
