Palladium nanoparticles stabilised by cinchona-based alkaloids in glycerol: Efficient catalysts for surface assisted processes

Palladium nanoparticles (PdNPs) were synthesised and fully characterised, both in solution and the solid state, using naturally-occurring cinchona-based alkaloids in neat glycerol. These nano-systems were stable under reaction conditions, finding applications in hydrogenation and hydrodehalogenation processes, as a result of their surface-like behaviour. Their reactivity was improved in relation to that involving PdNPs stabilised by phosphines and also by Pd/C as a heterogenous catalyst, mainly in terms of recyclability. In particular, the colloidal palladium catalyst stabilised by quinidine was highly efficient to promote the hydrodechlorination of aromatic compounds under low dihydrogen pressure. These original catalysts found applications in the synthesis of secondary and tertiary amines including N-substituted anilines, by means of one-pot tandem Pd-catalysed methodologies under smooth conditions. In all of these processes, glycerol performed a crucial function as a liquid support for the immobilisation of nanoparticle-based catalysts, allowing both the stabilisation of the nano-catalysts and easy recycling of the catalytic phase.

Alkyl substituent effects on J- or H-aggregate formation of bisazomethine dyes

Bisazomethine dyes with terminal alkyl substituents of different chain lengths (BAR: R = 1, 2, 3, 4, 5 and 6) were synthesized and deposited on a glass substrate to investigate the effect of the alkyl chain length on aggregate formation. Methyl- and ethyl-substituted bisazomethine dyes (BA1 and BA2) formed J-aggregates in thin films (ca. 50 nm), whereas, propyl-, butyl-, pentyl- and hexyl-substituted derivatives (BA3, BA4, BA5 and BA6) formed H-aggregates in thin films (ca. 50 nm). The aggregate formation of the BARs changed drastically between ethyl- and propyl-substituents (BA2/BA3). However, no remarkable changes were observed in the surface morphologies of BA2 and BA3 films. It is suggested that the critical determinant of aggregate formation of BAR is the molecular packing in the film, which depends on the chain length of the terminal alkyl substituent.

A novel strategy for N-alkylation of primary amines+

N-alkylation of primary amines has been carried out with alkylbromide using commercial Me2SO and K2CO3 as a base. This process offers a method of selection for obtaining either mono or dialkyl amines.
