摘要

2,2,6,6-Tetramethylpiperidino-tert-butylimino borane, la, and 2,2,6,6-tetramethyl-piperidino-2,6-diisopropylphenylimino borane (1b), react with the trichlorides of Al, Ga and In or with AlBr3 to 1:1 to give the addition products tmp = B = N(ECl3)tBu (E = Ga (2a), In (2b) and tmp = B = N(EHal(3))(C6H3,2,6-iPr(2)), (E = Al, Hal = Cl, (2c), E Al, Hal = Br (2d)). E = Ga, Hal = Cl (2e). All these compounds have an allene type structure with short BN bonds as shown by the determination of the crystal structures of 2a, b. NMR data are in accord with this structure. No isomerization to tmp-BHal-NR-EHal(2) has been observed at temperatures up to their melting points.
