Mesoporous nickel hydroxyapatite nanocomposite for microwave-assisted Henry reaction
摘要:
The utility of nickel hydroxyapatite nanocomposite (Ni-HAp) as a green catalyst for solvent free, microwave-assisted Henry reaction using nitromethane and a series of aromatic aldehydes as substrates is presented. The selected catalyst performed well to afford the respective nitrostyrenes which were quantified by gas chromatography equipped with a mass spectral detector (GC-MS). A few of the products were identified from the respective nuclear magnetic resonance (NMR) spectral data. (C) 2012 Elsevier Ltd. All rights reserved.

The generation and subsequent use of unstabilised azomethine ylides in dipolar cycloaddition reactions within a flow microreactor is demonstrated. The 3-nitropyrrolidines produced were furthermore subjected to chemoselective hydrogenation reac- tions using the H-Cube ® system. To ensure product purities in ex- cess of 90-95%, immobilised scavengers were successfully employed.
