- W2081799319 abstract "Die Bis(dialkylamino)azidoborane l a und l b, die Dialkylaminodiazidoborane 2 a und 2 b, Diäthylaminoazidophenylboran (3) und die Dialkoxyazidoborane 4 a und 4 b erhält man aus den entsprechenden Chlorboranen durch Azidierung mit LiN3 bzw. (im Falle von 4a) mit Bu3SiN3. Die Monoazidoborane 1, 3 und 4 zerfallen in kinetisch kontrollierbarer Weise mit nennenswerter Geschwindigkeit erst oberhalb 250°; neben N2 erhält man harzige Produkte, aus denen sich durch Verseifung die aus einer Umlagerungsreaktion hervorgegangenen Amine Ät2NNH2 (aus l b), PhNH2 (aus 3) bzw. CH3ONH2 (aus 4a) freimachen lassen. Der thermische Zerfall der Diazidoborane 2a und 2b bei 210° liefert neben N2 die salzartigen Azide (NH4)N3 bzw. (Nät2H2)N3. Der thermische Zerfall von l a in Cyclohexen führt unter Beteiligung des Lösungsmittels zum Diazadiboret-Derivat 6. Tetraaminodiazadiborete 10 a und 10 b sind neben Trisaminoboranen die Hauptprodukte des photolytischen Zerfalls von l a und l b. Boron Azides, X Aminoazidoboranes and Alkoxyazidoboranes The bis(dialkylamino)azidoboranes l a and 1b, the dialkylaminodiazidoboranes 2a and 2 b, diethylaminoazidophenylborane (3), and the dialkoxyazidoboranes 4 a and 4 b are formed from chloroboranes, chlorine being substituted by the N3-group with LiN3 or Bu3SiN3, respectively, as substitution agents. The monoazidoboranes 1, 3, and 4 are decomposed in a kinetically controlled manner at a noticeable rate only beyond 250° C; hydrolysis of the polymeric material gives the amines Et2NNH2 (from 1b), PhNH2 (from 3) and CH3ONH2 (from 4 a), respectively, indicating a rearrangement process during the thermolysis. The saltlike compounds (NH4N4 and (Et2NH2)N3, respectively, are the main products from the decomposition of the diazidoboranes 2a and 2b at 210°. The thermal decomposition of la in cyclohexene yields under participation of the solvent the diazadiborete derivative 6. From the photolytic decomposition of 1a and 1b, respectively, trisaminoboranes (as dismutation products) and the tetraaminodiazadiboretes 10 a and 10 b (as rearrangement products) are isolated." @default.
