METHOD OF PRODUCING N-SUBSTITUTED (2-TRIMETHYLSILYL-2-DIALKOXYPHOSPHORYL)ACETAMIDINES Russian patent published in 2011 - IPC C07F9/40

Abstract RU 2427583 C1

FIELD: chemistry.

SUBSTANCE: disclosed is a method of producing N-substituted (2-trimethylsilyl-2-dialkoxyphosphoryl)acetamidines, involving reaction of C-phosphorylated acetamidines with sodium followed by silylation of the obtained sodium derivative of trimethyl chlorosilane in a dioxane medium in molar ratio C-phosphorylated acetamidine: sodium: trimethyl chlorosilane = 1:1:1-1.1, respectively, and temperature 20-50°C. Novel N-substituted (2-trimethylsilyl-2-dialkoxyphosphoryl)acetamidines of formula: , where R¹=i-C₃H₇, C₄H₉; R²=N(C₂H₅)², N(C₃H₇)₂, N(C₄H₉)₂, , are obtained with output of over 80%.

EFFECT: high output.
