The reaction of 1,3‐dimercaptobenzene with iPr2PCl in the presence of the base NaH, furnishes the symmetric ligand [C6H4‐1,3‐(SPiPr2)2] (1a). The direct reaction of this ligand as well as of the literature‐known nonsymmetric ligand [C6H4‐1‐(SPiPr2)‐3‐(OPiPr2)] (1b) with NiCl2 affords the symmetric bis(thiophosphinito) PSCSP pincer complex [{C6H3‐2,6‐(SPiPr2)2}NiCl] (2a) as well as the phosphinito–thiophosphinito POCSP pincer complex [{C6H3‐2‐(SPiPr2)‐6‐(OPiPr2)}NiCl] (2b). Both complexes were fully characterised and their catalytic performance in Kumada coupling of aryl halides and p‐tolylmagnesium bromide under mild conditions was evaluated.

The employment of clays in industry and on laboratory scale is still of interest, despite their long history. The chemical-physical characteristics of such material are strongly related to their geographical origin and the availability of proper characterization techniques is of great importance in order to gain as more information about their behavior when utilized as filling materials. In the present contribute a physical characterization by meaning of Thermogravimetry, N2 physisorption, , XRD and SEM analyses of samples of commercial bentonite collected from the north of Sardinia (Italy) is reported.

This research revealed the importance of public service web portals for an e-government information system. An e-government portal is interacting with its administrators, citizens, businesses and other governments helping them increase their operations performance. The authors have developed, modeled, formulated and compared an efficient assessment framework for e-government portals. In order to accomplish such task many quantitative factors and indicators were taken under consideration; also, other frameworks have been studied and compared. The authors focused on the web portals services quantity that the interested parties should use, in order to create an well designed public services’ web portal. This research provides a framework model to evaluate the basic common digital public services that a government offers to its interactive stakeholders, so that all other countries across the world can predefine weaknesses and strengths, improve existing or formulating new e-services. The importance of the assessment framework model is thoroughly explained through the results.
