Abstract
The iminoboranes RB≡NR′, 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 . 7a-f. The Δ2:-tetraazaborolines . 8a-f, are the (3+2)-cycloaddition products from 2a-f and azides X′N3. A CH-bond of cyclopentadiene adds to one of the BN bonds of 2f, giving a mixture of the corresponding 1,3- and 1,4-cyclopentadienyl boranes. 9f, 9′f.Keywords
