Linkage isomerism and C–H activation in an ytterbium(ii) tetraphenylborate
Abstract
Reaction of [Yb{N(SiMe3)2}2(thf)2] with [Me3NH][BPh4] (1∶1) in PhMe gives a mixture of products including [Yb{N(SiMe3)2}(thf)BPh4] (1), which exhibits two structural forms, and [Yb{N(SiMe3)SiMe2CH2BPh3}(thf)2] (2) with an unusual silylamidoborate
