| titleOfInvention | Preparation of aminoboranes |
| abstract | A polymer having as the sole recurring unit the grouping -B(R)-N(Rd)-Re-N(Rc)- is formed by a transamination reaction between a bis (alkylamino) borane, tris (alkylamino) borane, bis (phenylamino) borane, or tris (phenylamino) borane, and a primary or secondary aliphatic or aromatic diamine or triamine, a mixed aliphaticaromatic diamine, or an aminotriazine. A homopolymer having the recurring unit -Re -B(R)-N(Rd)- is formed by a transamination reaction between molecules of an alkyl alkylamino aminoalkyl borane or an aromatic or aliphatic-aromatic analogue thereof, this reaction being effected by heating the aminoborane in question. In the above formulae, R is an alkyl, aryl, alkaryl, aralkyl, aminoalkyl, aminoaryl, aminoalkaryl or aminoarakyl radical, Rc and Rd represent hydrogen atoms, C1-C18 alkyl groups, phenyl, substituted phenyl, alkylamino or phenylamino radicals, and Re is an alkylene, phenylene or other divalent organic radical. Novel polymers specified are those obtained from melamine and tris (isopropylamino)- borane, from hexamethylene diamine and phenyl bis (t-butylamino) borane, and from p-phenylene diamine and tris (n-butylamino)-borane.ALSO:An aminoborane is made by effecting a transamination reaction between an amino-borane having in its molecule one or more amino radicals which are not desired in the product, or a substituted borazole corresponding thereto, and a primary or secondary amine corresponding to an amino radical which is desired in the product. For example R3-zB(N Ra Rb)z-x (NRcRd)x is made from R3-zB (N Ra Rb)z and HN Rc Rd where Z is an integer from 1 to 3, X is less than or equal to Z, R is an alkyl, aryl, alkaryl, aralkyl, aminoalkyl, aminoaryl, amino-alkaryl or aminoaralkyl radical, and Ra, Rb, Rc and Rd are each a hydrogen atom, or a C1-C18 alkyl group, or a phenyl, substituted phenyl, alkylamino or phenylamino radical. The reaction proceeds at room temperature but heating may be advantageous. Tris-(n-butylamino) borane, tris (phenylhydrazino) borane and methyl-bis (n-butylamino) borane are novel compounds. An aminoborane enriched in N15 isotope may be made using an amine enriched in N15 isotope as a reactant. |
