In this work, an efficient and green procedure for the synthesis of various substituted 1,5-benzodiazepine derivatives via a one-pot three-component catalytic reaction has been described. The reaction was conducted between o-phenylenediamine, dimedone and aldehyde derivatives in the presence of CuFe2O4 nanoparticles as a magnetic heterogeneous nanocatalyst under ball-milling conditions at room ...

In this investigation, a facile and green sonochemical route has been developed for the synthesis of 2-Ketomethylquinolines by using 2-methylquinolines and several acyl chlorides in the presence of nanocrystalline MgAl2O4 as an efficient heterogeneous catalyst. The combination of nanocatalyst and ultrasonic process afforded corresponding ketomethyl quinolines in shorter re...

A synergetic effect of ultrasonic irradiation and yolk–shell nanocatalyst was examined for the synthesis spirooxindoles from isatin, malononitrile cyclohexanone. It found this contributory can be accelerated desired reaction toward obtaining highly pure products in excellent yields short times. The contains melamine anchored onto magnetic Fe3O4 nanoparticles were applied as active base catalyst...

Platinum-cerium oxide hybrid nanocatalysts (CeO(2)-Pt) were for the first time designed as bionanolabels for highly efficient electrochemical immunosensing of low-abundance proteins coupling nanocatalyst-based redox cycling with in situ signal amplification strategy.

Self-assembled solution micelles prepared from polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) and polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP), have been employed as templates to synthesize copper nanocatalysts which are regarded as an excellent catalyst system for 1D nanomaterial synthesis. We have demonstrated that uniform-sized nanoparticles with diameters ranging from 1 to 15 nm have be...

A thermosensitive nanocatalyst was prepared in the reaction of water-soluble iron(III) porphyrins and thermosensitive polymeric nanospheres with a core-shell structure; its catalytic activity in cyclohexene oxidation by iodosylbenzene was dependent markedly on reaction temperatures in aqueous solution.

A strategy for the electrochemical detection of DNA based on catalytic hairpin assembly combined with nanocatalyst label-based redox cycling reaction signal amplification. A superior detection limit of 0.3 aM toward DNA can be achieved.

Fe3O4@Silicapropyl@Vanillin/Thiamin nanoparticles were synthesized by a simple immobilization method using cheap and natural materials. The nanocatalyst was analyzed XRD, FT-IR, FE-SEM, TEM, VSM TGA techniques applied as new, effective magnetically recoverable solid acid for the synthesis of azo-linked benzo[d]imidazoles or bis via reaction corresponding aldehydes 1,2-diaminobenzene in water gr...
