Silicon-containing explosives: Syntheses and sensitivity studies of (azidomethyl)-, bis(azidomethyl)-, and tris(azidomethyl)silanes

Abstract

A series of (azidomethyl)silanes [Me 3SiCH 2N 3 (1b),Me 2Si(CH 2N 3) 2 (2b), MeSi(CH 2N 3) 3 (3b), (CH 2) 4Si(CH 2N 3) 2 (4b), and (CH 2) 5Si(CH 2N 3) 2 (5b)] was synthesized, starting from the corresponding (chloromethyl)silanes 1a-3a or (iodomethyl)silanes 4a and 5a. Compounds 1b-5b were characterized by NMR, IR, and Raman spectroscopy. The thermal stabilities of the (azidomethyl)silanes 1b-5b were investigated by DSC, and their impact and friction sensitivities were measured with standard BAM methods. According to these studies, the tris(azidomethyl)silane 3b has to be classified as an extremely sensitive compound. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
