The reaction of trialkylboranes, e.g. triethylborane (Et3B), tripropylborane (Pr3B), or 9-alkyl-9-borabicyclononane , with either aceto-, propio-, butyro-, pivalo-, and benzonitrile gives, depending on the reaction conditions used or the nitrile employed, either the substituted diazoniadiboratetidines (1a-c), products of partial hydroboration, or by condensation of two or three nitrile molecules, with or without a concomitant hydroboration, the C3BN2 heterocycles 2a-c, 8a/b, 9a-d, and 10a/b(X-ray structure analysis of 2a and 10b).
