- Abstract
Abstract: The first soluble barium boryloxides [Ba]– OB{CH(SiMe3)2} are presented. These mono‐ or dinuclear complexes feature low coordination numbers, as low as two for [Ba(OB{CH(SiMe3)2}2)2], which is further stabilized by intra‐ and intermolecular Ba⋅⋅⋅H3C agostic interactions. Barium boryloxides and the parent [Ba{N(SiMe3)2}2⋅(thf)2] catalyze the dehydrocoupling of borinic acids with hydrosilanes, providing borasiloxanes under mild conditions.
