METHOD OF PRODUCING CYCLIC HALOPHOSPHAZENES BY REACTING HEXAALKYLDISILAZANES WITH HALOPHOSPHAZAPHOSPHONIUM SALTS Russian patent published in 2020 - IPC C01B21/97 C08G79/02

Abstract RU 2729523 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing cyclic halophosphazenes. Cyclic halophosphazenes of general formula (PX₂= N)_n, where n = 3÷16, X = Cl or Br, are obtained by reacting oligomeric halophosphazaphosphonium salts of general formula [X(PX₂= N)_n-1-PY₃]⁺A or [PX₃=N-PY₃]⁺A, where A=PY₆^- or Cl^-, and X and Y=Cl, Br and hexaalkyldisilazane HN (SiR₃)₂ in an inert solvent.

EFFECT: method is characterized by low amount of used solvent and possibility of performing synthesis at room temperature.
