Abstract

New 3D polymeric succinates of rare-earths have been synthesised: [Sc2(C4H4O4)2.5(OH)], [Y2(C4H4O4)3(H2O)2]·H2O, [La2(C4H4O4)3(H2O)2]·H2O, and their structures solved by single crystal XRD. They were obtained as single phases, characterised and tested as heterogeneous catalysts as Lewis acids in the acetalization of aldehydes and as redox agents in the oxidation of sulfides showing them to be effective and selective catalysts, easy to recover and reusable. The scandium, yttrium and lanthanum oxides were also tested in the same catalytic reactions to prove the effect of the porous organo-inorganic framework.
