Abstract
Reaction of either 2-methyl-3-nitropropene (IS) or 2-methyl-1-nitropropene (X) with stoichiometric amounts of aqueous sodium hydroxide yields sodium 2-methyl-2- propenenitronate (XI); acidification of XI with dilute aqueous acetic acid at 0'results initially in formation (at least in part) of 2-methyl-2-propenenitronic acid (XII), tautomeric rearrangement of which occurs slowly to give mixtures of IX and X. Prolonged reaction of either IX or of X ...
