## Abstract The reaction of diethyl methyl phosphonoacetate (**1**) with hydroxylamine in NaOH solution resulted in the loss of one of the phosphorus ethyl groups, and yielded monoethylphosphonoacetohydroxamic acid (**2**) as the major product (79%) and diethylphosphonoacetic acid (**3**) as the mi
