Abstract

Abstract : Na8 {Ni[Ni(en)]2 Nb10 O32 }·28H2 O, representing the first example of trinuclear nickel-containing polyoxoniobate, has been synthesized. It was found to catalyze the epoxidation of 3-methyl-2-buten-1-ol with high conversion and selectivity. Abstract : An organic–inorganic hybrid polyoxoniobate, Na8 {Ni[Ni(en)]2 Nb10 O32 }·28H2 O (1 ) (en = ethanediamine), has been synthesized and characterized. It represents the first example of a trinuclear nickel-containing polyoxoniobate. The catalysis of1 for allylic alcohol epoxidation was investigated at room temperature in aqueous solution, and was found to catalyze the epoxidation of 3-methyl-2-buten-1-ol with high conversion (98%) and selectivity (94%). Furthermore, magnetic measurements showed that the compound exhibits ferromagnetic interactions.
