Kristallstruktur und spektroskopische Charakterisierung von Hexamethyl- disilazan-Aluminiumtrichlorid [(H₃C)₃Si]₂NH ∙ AlCl₃ / Crystal Structure and Spectroscopic Characterisation of Hexamethyl- disilazane-trichloroalum inum [(H₃C)₃Si]₂NH ∙ AlCl₃

Abstract

Silazane, Aluminate By reaction of hexamethyldisilazane with alu minium trichloride in hexane hexamethyldisilazane-trichloroaluminum [(H3C )3Si]2NH • A1C13 is formed. The adduct has been characterized by MS, IR, Raman, *H, 13C, 27Al, 29Si N M R spectroscopy, and by a crystal structure determination (1425 independent reflections, R = 0.035). The space group is Pbca with a = 1312,6(5), b = 1182,9(5), c = 1964,7(5) pm; Z = 8. [(H 3C)3Si]2N H • A1C13 forms monomeric units which have point sym m e try Ci and exhibit an A l-N bond length of 193,9(3) pm.

Selective Double Addition Reaction of an E‒H Bond (E = Si, B) to a C≡N Triple Bond of Organonitriles

“…There is an advantage that these reactions do not generate by-products theoretically and the compounds with an N−Si or N−B bond thus obtained are useful products for the synthetic intermediates in organic chemistry. For examples, disilylamines (double hydrosilylation product) act as precursors for the production of Si,N-containing polymers [1,2,3,4], amine ligands for organometallic compounds [5,6], and silylating [7] and coupling [8] agents. Borylamines (hydroborylation products) have been reported to show a unique reactivity as iminium ion generators [9].…”
