Name: 2-Chloro-5-pyridinesulfonyl chloride. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2-Chloro-5-pyridinesulfonyl chloride, is researched, Molecular C5H3Cl2NO2S, CAS is 6684-39-5, about Aqueous Process Chemistry: The Preparation of Aryl Sulfonyl Chlorides.
The use of aqueous acidic conditions for the preparation of arylsulfonyl chlorides from diazonium salts in the presence of copper salts, preferably CuCl, together with thionyl chloride as the sulfur dioxide source, has considerable advantages over recommended literature procedures, whereby reactions are carried out in acetic acid with minimization of water content of the solvent. The method was successful for a wide range of electron-deficient and electron-neutral aryl substrates. The sulfonyl chlorides are protected from hydrolysis by their low solubility in water, which results in direct precipitation from the reaction mixture in good yields (>70%) and high strength (>98% weight/weight). The aqueous process, which is addnl. safer and more robust, can be readily scaled up and has significant environmental benefits.
From this literature《Aqueous Process Chemistry: The Preparation of Aryl Sulfonyl Chlorides》,we know some information about this compound(6684-39-5)Name: 2-Chloro-5-pyridinesulfonyl chloride, but this is not all information, there are many literatures related to this compound(6684-39-5).
