Chugaev reaktion
WebDie Tschugajew-Reaktion (auch Chugaev-Reaktion oder Chugaev-Eliminierung) ist eine Namensreaktion aus dem Bereich der Organischen Chemie. Die Reaktion wurde 1899 … Chugaev discovered that dimethylglyoxime forms a scarlet solid upon reaction with nickel(II) ions. This reaction was one of the first "spot tests" for a metal ion. An adherent to the theories of Alfred Werner, Chugaev made several contributions to the chemistry of platinum. The salt [Pt(NH3)5Cl]Cl3 containing the chloropentammineplatinum(IV) ion, is called "Chugaev's salt". Other complexes prepared in his laboratory include [Pt(SEt2)4][PtCl4], [Pt(NH3)5OH]Cl3, [Os(S…
