Formation of the novel neopentylidenoborane Me₃Si(Bu^t)NBCHBu^tfrom the tantalum neopentylidene complex [(η-C₅H₅)Cl₂TaCHBu^t] by metathesis

Abstract

The aminoiminoborane Me₃Si(Bu^t)NB[graphic omitted]NBu^t reacts with the alkylidene complex [(η-C₅H₅)Cl₂TaCHBu^t] at –50 °C to give a (2 + 2) cycloadduct containing a [graphic omitted] ring; on warming to 0 °C cleavage occurs, affording the metathesis products Me₃Si(Bu^t)NBCHBu^t and [(η-C₅H₅)Cl₂TaNBu^t].
