In this study, efficient heterogeneous catalysts using metal hydroxides(supported metal hydroxide catalysts) have been developed. Various kinds of functional group transformations, e. g., oxidative dehydrogenation of alcohols and amines and oxidative homocoupling of alkynes can be promoted by the concerted activation of substrates by the Lewis acid and Bronsted base sites on supported metal hydroxide catalysts. In addition, we can successfully develop novel catalytic transformations with metal hydroxide catalysts,(1) direct oxidative synthesis of nitriles from primary alcohols and ammonia,(2) N-alkylation of ammonia(or its surrogates) with alcohols to produce symmetrically substituted tertiary or secondary amines, and(3) oxidation of organic azides to nitriles.
