The borylated carbodiimides 3 a, 3b and 4 can be synthesized by reaction of the 2-chloro-1,3,2-diazaborolidines 2a, 2b with Me3Si -N = C = N -SiMe3(1) or Me3Si -N = C = N -tBu respectively. In the reaction of the non cyclic haloboranes R2BHal (R = Ph, Me, Me2N) 2c -e with 1 R3B is formed and for R = Me, Me2N polymeric (RBNCN)nis obtained, whilst the spectroscopically identified intermediate products only in the case of R = Ph can be isolated. The chloroborolane 2f leads to the polymeric diborylated carbodiimide 3f, probably due to intermolecular B -N-coordination. H2N -CN forms with 9-BBN the monoborylated cyanamide 8 . |
