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 hydrochloride with dimethyldichlorosilane at temperature 20-25°C in dehydrated benzene medium for 2-2.5 h followed by cooling to 8-10°C and addition of triethylamine in the mole ratio of reagents alkyl-(2-methyl-2-hydroxy)propaneimidate : dimethyldichlorosilane : triethylamine = (1.0-1.05):1.0:(3.0-3.2), respectively. Invention provides expanding assortment of chemical compounds and preparing new substituted of 1,3,2-oxazasilols with the yield 75%, not less.
EFFECT: improved method for preparing.
