FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention describes a method for preparing substituted 1,3,2-oxazasilols of the general formula: 
wherein R is C2H5, i-C3H7, C4H9. Method involves interaction of alkyl-(2-methyl-2-hydroxy)-propaneimidate with dimethyldichlorosilane in the presence of triethylamine in dehydrated benzene medium and in the mole ratio alkyl-(2-methyl-2-hydroxy)-propaneimidate : dimethyldichlorosilane : triethylamine = (1-1.05):(1-1.01):(2.1-2.2), respectively, at temperature 10-15°C. Invention provides expanding assortment of chemical compounds and preparing new substituted 1,3,2-oxazasilols with the yield 65%, not less.
EFFECT: improved method for preparing.
