The advantages of using 2-amino-5-nitrothiazole is a liquid with a similar aroma to almond, found in potato seeds. Acid conditions are easy to hydrolysis to benzaldehyde, but not affected by alkaline environment, on the oxidant or reducing agent temperature, it is an important form of preservation of benzaldehyde. advantages of using 2-amino-5-nitrothiazole can be used as a raw material for edible flavor and daily chemical flavor, and also as a reagent for the synthesis of selenium carbonyl compounds.
preparation
CN201811481556 reported a method of synthesizing aromatic acetals from styrene under visible light. 8-10mg catalyst Ir/ZnIn2S4 was added into the reaction tube, and a certain proportion of styrene and mercaptan (molar ratio of styrene to mercaptan is 1.2:1-1:1) and 4ml alcohol were added. Then the reaction tube is irradiated under normal temperature, atmospheric pressure, air atmosphere and visible light for 8-15h. Mercaptan generates sulfur radical under the action of Ir/ZnIn2S4 and visible light, which reacts with styrene to form alkyl radical, and then generates peroxygen radical under the action of O2 in the air, which then reacts with alcohol to form acetal. The method does not require the addition of protic acid or Lewis acid, and the reaction time is 8-15h.
