| Abstract: The substitution reaction of quinine by the 18 types of heteropoly complexes, for these formed compounds are Keggin structure and the molecular formulas are [XM11O39M′(OH)2]6-(X=Si,Ge,P;M=Mo or W;M′=Co,Ni,Cu), was studied by the means of phase transfer. The results of characterization that were accomplished by UV and ESR indicated that the quinine does form the chemical bond with the hetropoly ligands. Spectral experiment demonstrated that the structure held the same when the heteropoly complex contained Cu2+ was reacted with qui-nine, while the heteropoly complex contained Ni2+ resulted in the changing of the structure. Such a result of op-tical rotatory opticity testified that quinine reacting with heteropoly acid contained transitional metals could form a kind of new complexes which were optical rotation. |
