Organometallic Complex Synthesis and Catalysis

Derivatives of 1-aza-2-bora-3-oxacyclopentane are easily prepared by cleavage of the N-Si and O-Si bonds in disilylated ethanolamines with halogenoboranes. The B-halogeno and B-hydro compounds with NH and N-CH 3 moieties are associated in the solid state, and in part also in the liquid and gas phase. In the solid phase hexahydroborazine derivatives are formed by association. Further compounds include B-N-Si-substituted rings and interlinked bicyclic systems.
