A series of N-organosilylalkyl-substituted ethylenediamines, R3Si(CH2)n-NHCH2CH2NH2 (R = CH3, C6H5 or 4-CH3C6H4 n = 1 or 3), were prepared by the reaction of haloalkylsilanes with ethylenediamine. The cleavage of a methyl group from silicon by concentrated sulfuric acid was used for the preparation of 1,3-bis-[N-(2-aminoethyl)aminomethyl]-1,1,3,3-tetramethyldisiloxane. The proton and carbon-13 NMR spectra of these compounds are reported.
