Abstract A facile access to the synthesis of alkyl and aryl oxime esters of ketoximes and aldoximes in high yields (90–97%) is reported. The reactions were performed using N-[3-(methylamino)propyl]-N′-ethylcarbodiimide hydrochloride (EDCI) reagent in the presence of 4-(dimethylamino)pyridine (DMAP) as a catalyst at room temperature. The isolation and purification of products is very simple and in cases

action of chlorine on oximes in hydrogen fluoride as a medium gives gem-dihalogenoalkanes. The reaction proceeds through the intermediate formation of gem-chloronitrosoalkanes. The relative proportions between gem-dichloro, -difluoro and -fluorochloro compounds are dependent on the presence of a cosolvent. The use of other oxidants, such as nitricoxide, dinitrogen tetroxide or nitrosylchloride, gives
