摘要：

[2 + 2] Cycloaddition of Iminoboranes to a Neopentylidenetantalum Complex The neopentylidene complex(η‐Cp)cl2Ta=CHtBu (1) and the iminoboranes R′B≡NR (2a–d, R′/R = Et/tBu, Bu/tBu, iBu/ iBu, Ph/tBu) undergo a [2 + 2] cycloaddition yielding the corresponding 1‐aza‐2‐bora‐4‐tantalacyclobutanes 3a–d. The crystal and molecular structure of 3c is reported. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
