The aminoiminoborane 2 adds protic reagents of type HX (X=OH, OR, OCOR, SH, SR, NH2, NHR, NHNR2) across the formal BN triple bond regiospecifically forming (tert-butylamino)(2,2,6,6-tetramethylpiperidino)boranes (3-7, 12, 13, 15, 16a, b, 17-27) which are inert towards ligand redistribution.The relative rates of addition are primarily governed by steric factors (NH3 > NH2R > HNR2; HOR > HSR >HNR2).Bulky amines HNR2 will not add to 2.Excess HX (X=OH, OR, OC(O)R)reacts with the boranes formed on 1:1 addition by breaking BN bonds; however, no prediction can be made concerning which BN bond in tmpBX will be cleaved.
