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. Ba–boryloxides and the parent [Ba{N(SiMe3)2}2.(thf)2] catalyze the dehydrocoupling of borinic acids with hydrosilanes, providing borasiloxanes under mild conditions. %G English %2 https://univ-rennes.hal.science/hal-01862088/document %2 https://univ-rennes.hal.science/hal-01862088/file/Ba-boryloxides_ANIE_201807297_HAL.pdf %L hal-01862088 %U https://univ-rennes.hal.science/hal-01862088 %~ UNILIM %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ SPCTS %~ ISCR %~ IPAM %~ SCR-CD %~ SCR_OMC2012 %~ ISCR-OMC %~ UR1-SPM %~ ISCR-PRATS %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ IRCER %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MMS %~ IMPEO %~ TEST2-HALCNRS
