Reactions of Hexaphenyldilead with ?-Diketones and ?-Ketoesters

Abstract

The reactions of hexaphenyldilead with β-diketones and β-ketoesters in the molar ratio of 1:2 were studied in anhydrous benzene. Complexes of the type R₃Pb-L (where R= -C₆H₅ and L = β-diketones or β- ketoesters) have been synthesized. All the reactions were found to be quite facile. It was observed that lead-lead bond was cleaved. The resulting derivatives of organolead(IV) were obtained in the form of yellow solids. They are quite stable to atmospheric moisture and are insoluble in common organic solvents. The lead atom is probably pentacoordinated and structure is trigonal bipyramidal.
