FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing thionylamide cyan-anhydride of methylphosphonic acid of formula CH3P(O)(CN)N=S=O, which can be used as a semi-finished product in organophosphorus synthesis. The disclosed method lies in obtaining the end product by reacting thionylamide chloroanhydride of methylphosphonic acid with alkoxydimethylsilylcyanides of general formula (CH3)2Si(OR)CN, where R = CH3, C2H5,C3H7, i-C3H7 at 40°C for 20 minutes.
EFFECT: design of a new method of producing organophosphorus compounds.
