Oximes
« on: January 23, 2014, 09:38:43 PM »
Hi everyone! i've been doing some research about the formation of oximes from aldehydes and was wondering what is the easiest way that also gives the best yields.

I am using hydroxylamine and sodium carbonate. ( would NaOH be better ) also is stirring necessary?

For the moment I am mixing my aldehyde in Etoh, adding hydroxylamine in H2O, adding sodium carbonate, stir about 4h then let everything cool over night in a ice bath.

What would be your suggestions?

I used to use the procedure in Curtin, Shriner, and Fuson, but I think you may find textbooks report the mechanistically optimal pH for the reaction is 4.
