When di(isobutylamino)phenylboron is pyrolysed, isobutylamine is eliminated and the trimer, B-triphenyl-N-tri-isobutylborazine, is produced. Contrary to claims in the literature, the pyrolysis does not provide a route to linear boron–nitrogen polymers.

The reactions of Grignard reagents with tri-B-chlorotri-N-isopropylborazole and with four tri-N-alkylborazoles having branched alkyl groups have been studied, and methods for the preparation of some mono-, di-, and tri-B-substituted derivatives are described. Stepwise substitution of tri-N-isopropyl- and tri-N-s-butyl-borazoles occurs. The reactions were followed by gas–liquid chromatography. The infrared
