Transesterification of methyl[N-alky(aryl)aminomethyl]-diethoxysilanes with furfuryl and tetrahydrofurfuryl alcohols gives four new substituted furfuryloxysilanes and three new substituted tetrahydrofur-furyloxysilanes, with a secondary or tertiary amino group in the organic group. Some of the physical properties, as well as the IR spectra of the compounds, are given.
