The iminoboranes RBNR', 2a-f, are formed by the elimination of Me3SiHal from the corresponding aminoboranes 1a-f.Stabilization occurs either through cyclodimerisation (-->3b-d,f), cyclotrimerisation (-->4e), bicyclotrimerisation (-->5b) or cyclotetramerisation (-->6a).Trialkylboranes BX3 are added to give the diboryl amines RXBN(R')BX2, 7a-f.The Δ2-tetraazaborolines (R)B(R')N-N=N-N(X')>, 8a-f, are the (3-2)-cycloaddition products from 2a-f and azides X'N3.A CH-bond of cyclopentadiene adds to one BN bonds of 2f, giving a mixture of the corresponding 1,3- and 1,4-cyclopentadienyl boranes, 9f, 9'f. - Keywords: Iminoboranes, Cyclodimers, Cyclotrimers, Cyclotetramers
