Abstracts:                        An efficient methodology employing copper nanoparticles for the preparation of 2-naphthol condensed 1,3-oxazinone derivatives employing one-pot condensation reaction in the presence of K2CO3 and copper  nanoparticles in PEG-400 is described which offers several advantages, viz. high yields, clean reaction, short reaction times, recyclability of the catalyst and simple workup procedure. PEG-400 was found to be the best solvent out of a range of solvents examined for this scheme. Moreover, PEG could stabilize the nanoparticles from oxidation and thus could increase the catalyst efficiency by escalating the TON (Turn over Number) and TOF (Turn over Frequency) of the catalyst, making the protocol greener, eco-friendly and environmentally benign.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
