Cobalt-doped hybrid materials consisting of metal oxides and carbon derived from chitin were prepared, characterized and tested for industrially relevant nitrile hydrogenations. The optimal catalyst supported onto MgO showed, after pyrolysis at 700 °C, magnesium oxide nanocubes decorated with carbon-enveloped Co nanoparticles. This special structure allows for the selective hydrogenation of diverse and demanding nitriles to the corresponding primary amines under mild conditions (e.g. 70 °C, 20 bar H2). The advantage of this novel catalytic material is showcased for industrially important substrates, including adipodinitrile, picolinonitrile, and fatty acid nitriles. Notably, the developed system outperformed all other tested commercial catalysts, for example, Raney Nickel and even noble-metal-based systems in these transformations.

Novel alkylamine fluorophosphates of the formula: STR1 wherein R is a linear or branched alkyl group containing 1-20 carbon atoms; R1 is lower alkyl or hydrogen, R2 is alkyl or hydrogen; X is 1 or 2; Y is 1 when X=1; Y is 1 or 2 when X=2; m and n are positive whole integers whose sum is 3. When R, R1 and R2 are alkyl they can be substituted with an hydroxy group. The novel fluorophosphates have been found to be effective in reducing the acid solubility of tooth enamel.
