Core–shell nanocatalysts are attractive due to their versatility and stability. Here, we describe cobalt nanoparticles encapsulated within graphitic shells prepared via the pyrolysis of a cationic poly-ionic liquid (PIL) with a cobalt(II) chloride anion. The resulting material has a core–shell structure that displays excellent activity and selectivity in the self-dehydrogenation and hetero-dehydrogenation of primary amines to their corresponding imines. Furthermore, the catalyst exhibits excellent activity in the synthesis of secondary imines from substrates with various reducible functional groups (C=C, C≡C and C≡N) and amino acid derivatives.

Supported ruthenium complexes based on electron-rich (NHC)NN-pincer-type ligands selectively catalyze the formation of substituted amines from nitroaromatics and carbonyl compounds through a series of consecutive steps which involves the reduction of nitro group to amine, the formation of an imine or iminium ion intermediate, followed by in situ reduction to an alkylated amine of higher order in a single operation. Solid complexes result active and recyclable catalysts and no deactivation was observed after repeated recycling.

, p. 265 - 266 (2007/10/02)
N-(4-alkoxybenzylidene)-4-halogenoanilines have been synthesized, and phase transitions determined using a differential scanning calorimeter and a polarizing microscope.Smectic and nematic phases have been observed for fluoro and chloro derivatives whereas bromo and iodo derivatives exhibit only a smectic phase.
