I have a question regarding oxime formation.
I have a reaction to synthetise oxime by NH2OHxHCl/KOH and another with NH2OHxHCl/HCl conc.
I tought that the one with HCl reagent was bad because of Beckmann rearrangement in acidic media, but it seems that it work. Does anybody have an explanation of why this rearrangement don't occur if we have a strong acidic solution?
Furthermore, i found almost everywhere that the synthesis of the oxime is done with HCl, but my procedure with KOH work just fine. I don't understand why.
Could somebody enlight me with the oxime formation and in wich condition i should NOT place this fonctionnal group?
