FIELD: organic chemistry.
SUBSTANCE: invention relates to the field of organic chemistry. Proposed are diphenyltetraoxasilaspiroalkanes of formula (1) and a method for their preparation by interaction of gem-dihydroperoxides with bis(methoxymethyl)diphenylsilane in the presence of La(NO3)3⋅6Н2О catalyst.
EFFECT: proposed diphenyltetraoxasilaspiroalkanes expand the range of hydroxylation, peroxidation and oxidation reagents in the preparation of polymers, and the proposed method of preparation allows one to obtain diphenyltetraoxasilaspiroalkanes selectively and in good yield.
