Abstract

1:2‐Komplexe von Halogensilanen mit Bipyridin bilden sich, wenn im Silan mindestens zwei Si‐J‐Bindungen vorliegen und Chloroform als Lösungsmittel verwendet wird: Bildung der Komplexe (II) aus den Silanen (I).

Complexes of germanium chlorides (RnGeCl4-n, n=0-3; R=Me, Ph) with redox active N-hetero­aromatic ligands: an electrochemical study

“…Similar complexes of 2,2′ -bipyridine (bipy) with silicon halides have been prepared, e.g., with Ph 3 SiX (X = Br, I) (Corey and West, 1963); with RSiCl 3 (Kummer et al, 1990); with perhalodisilanes Si 2 X 6 (X = F, Cl, Br), mixed methylhalodisilanes (Si 2 Me n X 6-n , X = Cl, I; n = 2, 3) and Si 3 Cl 8 (Kummer et al, 1979); with substituted iodides XYSiI 2 (X, Y = Cl, I, Me, H, Ph) (Kummer et al, 1977); and with Cl 3 SiOSiCl 3 (Kummer et al, 1987). By reaction of Si 2 Cl 6 with bipy in tetrahydrofuran, a silylene complex, (bipy) 2 ‧ SiCl 2 and bipy ‧ SiCl 4 , can be obtained (Kummer et al, 1969).…”

Discovery of an Octahedral Silicon Complex as a Potent Antifungal Agent

“…Several years ago, one of us reported the first examples of designed biologically active complexes based on octahedral silicon and found that silicon complexes can be viewed as template-substituent of ruthenium complexes [ 11 , 12 , 13 ]. As a structural octahedral center, the metalloid silicon owns distinct advantages over transition metals, such as a lack of toxicity concerns and high stability in configuration [ 14 , 15 ]. Similarly, as the octahedral polypyridyl ruthenium complexes, hexacoordinate silicon arenediloate complexes could intercalate and remarkably stabilize DNA duplex, which means enormous biological application potentiality [ 16 , 17 , 18 , 19 , 20 ].…”
