Autor: Liliane G. Hubert-Pfalzgraf, Jacqueline Vaissermann, Valérie Abada

Publikováno v: Polyhedron. 18:3497-3504

The addition of pinacol to mixtures of titanium and cerium isopropoxides as well as the use of insoluble titanium and cerium pinacolate synthons was investigated as a route to M-Ce (M=Ti, Nb) species. Pinacol was able to promote the formation of mixe
