A series of vanadia catalysts with various V2O5 loadings supported on SnO2 and alpha-Sb2O4 are investigated by the application of X-ray diffraction and solid-state 51V and 1H NMR techniques. XRD results show no evidence for the formation of a crystalline vanadia phase on both supports. However, the
The reactions of SnC1, with the complexes cis-PtC1,P2, P = trialkyl and triaryl phosphines and phosphites, in CDC1, and CD2C12 have been studied using 31P and 195Pt NMR. methods. For equimolar amounts of Sn and Pt, products of the type PtCl(SnC13)P2 are formed with the complex geometry depending on
