Summary
The reaction of tetradentate azomethine ligands H2salen* [N,N′-ethylenebis(2–hydroxyacetophenoneimine)] or Hzsalen* [N,N′-ethylene-bis(3,5–di-tert-butyl-sali-cylideneimine)] with chlorosilanes produces silicon compounds with hexacoordinated silicon (salen)SiXY (X = Cl; Y = H, Cl, C, C6H5). Both ligands X and Y can be exchanged for fluorine. The crystal structure analysis of (salen*)SiF2 reveals the truly hexacoordination of the silicon atom. The chloro compounds (salen*)SiCl2 undergo Wurtz-type coupling reactions leading to oligosilanes with hypervalent silicon. Coupling of (salen*)SiCl2 with acetylides creates compounds with an Si-CEC-Si backbone.
