- Boron-nitrogen compounds. XXV. Substituted 1,3,2-diazaboracycloalkanes
-
Boron- and nitrogen-substituted 1,3,2-diazaboracycloalkanes have been prepared by a transamination between bis(dimethylamino)boranes and α,ω-diamines. Partial substitution of the nitrogen of the diamine does not appear to inhibit this reaction; five-, six-, and seven-membered heterocyclic systems are readily obtained by the described procedure. However, the low yields of product obtained in those reactions involving an olefinic α,ω-diamine indicate that steric factors may play an important role. The mechanism of the formation of the boron-nitrogen-carbon heterocycles is discussed, and some spectroscopic data are briefly evaluated.
