Reaction of Hexamethyldisilazane with Borane in Tetrahydrofuran
摘要:
AbstractHexamethyldisilazane 1 reacts with borane in tetrahydrofuran (THFBH3, 2) first by formation of an adduct (Me3Si)2NHBH3 (3), and then either to the N,N‐bis‐(trimethylsilyl)‐μ‐aminodiborane 5 or to the mixture of 5 and N‐trimethylsilyl‐μ‐aminodiborane(6) 6, depending on the reaction conditions. The compounds 5 and 6 can be quantitatively converted to the N,N′,N″‐tris(trimethylsilyl)borazine 4. Three intermediates can be identified, namely N,N‐bis(trimethylsilyl)borane 7, N,N‐bis(trimethylsilyl)amino(N′‐trimethylsilylamino)borane 8 and N‐trimethylsilylaminoborane‐trimer. All products and intermediates were characterized by multinuclear NMR spectroscopy, and coupling constant 1J(29Si, 15N) were measured from 29Si NMR spectra by using the Hahn‐echo‐extended (HEED) INEPT pulse sequence.
