Mmmmmm....
According to:
A Practical and User-Friendly Method for the Selenium-Free One-Step Preparation of 1,2-Diketones and their Monoxime Analogs (Synlett,
2004)
there is no need to use any alkyl nitrite to prepare oximes.
They use THF(or dioxane)/NaNO2/HClaq to prepare these compounds.
More, there is suggestion that oximes (isonitrosoketones) of 1,2-diketones can be obtained in H2O/NaNO2/HClaq
in the case of soluble ketones.
My question is: Has anybody ever tried to prepare monooxime of biacetyl from MEK in this or similar way ??
