RESUMO
In this study, we present a convenient method for the synthesis of oxime ethers by reacting oximes with various chlorides (alkyl, functionalized alkyl, and benzyl) and with the subsequent use of a super base-pulverized potassium hydroxide in DMSO. The reactions take place at room temperature and the products are obtained in high yields. The final products were received within 2â min to 3â h. In addition, the compounds do not require chromatographic separation. The structure elucidation of the titled compounds was performed by using 1Hâ NMR and 13Câ NMR spectroscopy as well as mass spectrometry. The presented method of synthesis for oxime ethers is environmentally friendly, because neither water cooling or heating of the reaction mixture/solvents (necessary for chromatographic purification) is required. The synthesis can be carried out very easily on a large scale.
