METHOD FOR PRODUCING OLIGO[(N,N-DIMETHYLETHYLENEDIAMINO)-(TRIAZOLYL)PHOSPHAZENE] Russian patent published in 2023 - IPC C07B43/04 

FIELD: organic chemistry.

SUBSTANCE: invention relates to the field of organic chemistry and is aimed at obtaining a linear oligophosphazene for plant protection in agriculture and forestry. Disclosed is a method for obtaining oligo[(N,N-dimethylethylenediamino)-(triazolyl)phosphazene], which consists in the fact that oligodichlorophosphazene in the medium of dried tetrahydrofuran and triethylamine interacts with triazole for 72 hours at a temperature of 23°C, followed by the addition of N,N- dimethylethylenediamine, then incubated for 72 hours at a temperature of 23°C, the solvent is distilled off, dialysis is carried out against water and dried at a pressure of 6 Pa and a temperature of 0°C.

EFFECT: invention provides an efficient method for producing oligo[(N,N-dimethylethylenediamino)-(triazolyl)phosphazene].
