    • The present invention relates to a process for selective oxidation of a sulfide by the use of lithium molibdenate niobate (LiNbMoO6) - hydrogen peroxide oxidant system to the corresponding sulfoxide or sulfone compound within a few hours under the condition of controlling the amount of hydrogen peroxide in the presence of alcohol solvent. The process for oxidizing a sulfide according to the present invention has economic advantage in view of the application for industrial use as well as in a laboratory scale because the process is carried out under mild condition, comprising of simple procedure, and the reactants are easy to handle. In particular, allylic sulfides having double bond(s) of high electron density by alkyl substitution or extended conjugation, which are apt to be attacked by electrophilic oxidants, can be subjected to selective oxidation to sulfones or sulfoxides without oxidation of the double bond(s), according to the present invention.
    • 本发明涉及在控制过氧化氢的量的条件下,在几小时内使用铌酸铌酸锂(LiNbMoO 6) - 过氧化氢氧化剂体系对硫化物进行选择性氧化的方法 酒精溶剂的存在。 根据本发明的氧化硫化物的方法鉴于工业应用以及实验室规模具有经济优势,因为该方法在温和条件下进行,包括简单的步骤,并且反应物容易 处理。 特别地,易于被亲电子氧化剂侵蚀的通过烷基取代或延伸共轭具有高电子密度双键的烯丙基硫化物可以在不氧化双键的情况下进行选择性氧化成砜或亚砜 ),根据本发明。
