Padova system

Complexes based on titanium excess tartrate combination (the Padova system). In 1984, the same year the Orsay group developed their system, a group in Padova, Italy, headed by Modena,47 developed a different system, able to oxidize sulfides to sulfoxides with high selectivity, also based on a modification of the Sharpless catalyst. The Padova group used TBHP in the presence of 1 mol equiv of Ti(0-/-Pr)4/(/ ,/ )-DET, 1/4 combination. The reactions were performed at -20... 

It was hypothesized from the beginning that identical species could be involved in the two systems. The role of an excess of tartrate was to bring an uncontrolled amount of water into the system, based on the observation that the Padova system produces racemic sulfoxides by addition of molecular sieves.

The XPS investigations here described for the various oxide systems have been carried out using a Perkin Elmer O 5600 Multi Technique System located at the Department of Chemistry of the University of Padova (Italy), equipped with a dual Mg - A1 anode as the X-ray source. Magnesium and aluminium are the two materials used universally as anodes in soft X-ray sources (Mg Ka = 1253.6 eV, FWHM = 0.70 eV A1 Ka = 1486.6 eV, FWHM = 0.85 eV).
