1,1-Dimethyl-1-(trialkoxysilylmethyl)hydrazinium and 1,1-Dimethyl-1-(silatranylmethyl)hydrazinium Halides

Formerly unknown 1,1-dimethyl-1-(trialkoxysilylmethyl)- and 1,1-dimethyl-1-(silatranylmethyl)hydrazinium halides were prepared by reaction of 1,1-dimethylhydrazine with (halomethyl)trialkoxysilanes XCH₂Si(OR)₃ (X = Cl, I; R=Me, Et) and 1-(halomethyl)silatranes XCH₂Si(OCH₂CH₂)₃N (X = Cl, Br). 1,1-Dimethyl-1-(silatranylmethyl)hydrazinium chloride and iodide were also obtained by transetherification of corresponding 1,1-dimethyl-1-(trimethoxysilylmethyl)hydrazinium halides with tris(2-hydroxyethyl)amine.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 6, 2005, pp. 915–919.Original Russian Text Copyright © 2005 by Sorokin, Voronkov.
