Stable complexes are described, formed by mono- and di-functional compounds bound to nanoparticles composed of various types of transition metal oxides and of metals useful in the production processes of different types of new materials (such as for example some types of hydrophile plastics, fibers); processes for the production of the complexes are also described.
An efficient Rh(III)-catalyzed straightforward strategy is developed for the synthesis of quinoline braced cyclophane macrocycles via methyl (sp3) C–H functionalization. The method is mild, simple and regioselective with various ring sizes and has good functional group tolerance. The method proceeds via C8-methyl metalation, metal–carbene formation and a subsequent migratory insertion. High dilution
