Реферат: Process for the synthesis of new monohydrazides of malonic acid substituted, of the general formula I ** (See formula) ** where R1 means a hydrocarbon radical with 8 carbon atoms at most and R2 means a hydrogen or halogen atom, and its salts with inorganic and organic bases, characterized by treating a compound of the general formula II ** (See formula) ** where R1 and R2 have the same meaning as stated above, And it means hydrogen or the benzyloxycarbonyl radical and X means, as before, hydrogen or the benzyl radical, but nevertheless at most one of the two symbols X and Y is found for hydrogen, with sodium in liquid ammonia and by converting the compound of the general formula I obtained, if desired, into a salt with an inorganic or organic base.
