METHOD OF PRODUCING 1- AND 2-(3-(TRIMETHOXYSILYL)PROPYL)BENZOTRIAZOLES Russian patent published in 2025 - IPC C07F7/18 

FIELD: chemistry.

SUBSTANCE: invention relates to organosilicon chemistry, specifically to a method of producing 1- and 2-(3-(trimethoxysilyl)propyl)benzotriazoles by alkylation of (3-chloropropyl)trimethoxysilane of a sodium salt of benzotriazole. Method is characterized by that the sodium salt of benzotriazole is obtained from equimolar amounts of benzotriazole and sodium hydroxide by boiling with water separation in a toluene medium, and alkylation is carried out with (3-chloropropyl)trimethoxysilane while boiling the reaction mass for 3 hours, distilling, before introducing it into the reaction mass, half of the initial volume of toluene and adding an equal amount of dimethylformamide.

EFFECT: disclosed method is carried out using readily available starting reagents and a solvent, provides good output of end products and extends the range of methods for producing 1- and 2-(3-(trimethoxysilyl)propyl)benzotriazoles.
