Polar Iminoboranes: Reactions of (tert-Butylimino)(pentafluorophenyl)borane

The reactions of the iminoborane C6H5-BN-tBu (1) with nitriles and isonitriles are studied.Nitriles RCN give cycloadducts either of the triazadiboracyclohexane type (3a; R = iPr) or of the tetraazatriborabicyclooctane type or of the (iminomethyl)borazine type (5e,f; R = Me, Et).Isonitriles RNC yield mainly adducts of RNC to a cycloaddition product of the diazadiboracyclopentane type (6a,b; R = 2,6-C6H3Me2, tBu); the adduct of RNC to a diazadiboracyclobutane may be a side-product (7b; R = tBu).The iminoborane reacts with two molecules of (2,6-C6H3Me2)NC to give the corresponding azaboracyclobutane 8.The iminoborane tBu-BN-C6H5 (1'), formed by gas-phase elimination of ClSiMe3 from Cl(tBu)B=N(C6F5)SiMe3 (9), cyclodimerizes more readily than the isomeric borane 1.The cyclodimer 2' gives 1:1-addition reactions with tBuNC, PMe3, and MeNC, respectively; the added components fluctuate in solutions of the products 7b'-d'.A similar fluctuation is observed with the 1:1 adduct 7c from PMe3 and the cyclodimer 2 of the iminoborane 1.The products 3a, 5e, 6a, 8 crystallize in the space groups P21/c, P21/n, Pbca, and P21/c, respectively. - Keywords: Iminoborane / Triazadiboracyclohexane / Borazine / Diazadiboracyclobutane / Azaboracyclobutane / Diazadiboracyclopentane
