FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing methyl-phosphonic acid thionylamide esters of formula: CH3P(O)(OR)N=S=O, where R = i-C3H7, C4H9, i-C4H9, which can be used as semi-finished products in organophosphorus synthesis. The disclosed method lies in obtaining end products by reacting thionylamide choroanhydride of methyl-phosphonic acid with alkoxytrimethylsilanes of general formula (CH3)3SiOR, where R = i-C3H7, C4H9, i-C4H9 at 40-50°C for 2 hours.
EFFECT: design of a new method of producing the said compounds.
