Pentacoordinate silicon compounds based on 2,2′-dihydroxyazobenzene ligand

Abstract

The preparation and structures of 6,6-diorganylbenzo[d,h][1,3,6,7,2]dioxadiazasilonines containing the N→Si intramolecular dative bond are described. The complexes were characterized by NMR (1H, 13C, 29Si), IR and UV spectra. The crystal structures of 6-methyl-6-phenyl- and 6-(chloromethyl)-6-methylbenzo[d,h][1,3,6,7,2]dioxadiazasilonines were determined by X-ray diffraction.
