Summary

Our investigations on silicon compounds of ethylene-N,N'-bis(2-hydroxyacetophenoneiminate) led to the synthesis and X-ray structure analysis of a new kind of salen complex — hypervalent silicon compounds with a threefold deprotonated salen ligand and an enamine structure. This structural unit provides access to new routes for synthesizing hypercoordinate silicon complexes. Addition reactions between various Brønsted acids and these new pentacoordinate silicon compounds were carried out to precipitate complexes bearing hexacoordinate silicon atoms.
