Continuous flow of nitroso Diels–Alder reaction

Enhanced Reaction Efficiency in Continuous Flow

Continuous flow reactors are an enabling tool that can significantly benefit chemical reactions, especially those that are path length dependent (e.g. photochemical), mixing or transport dependent (e.g. gas-liquid), exothermic or utilize hazardous or unstable intermediates. In this review, we demonstrate how the nearly instantaneous mixing, exceptionally fast mass transfer, safe access to high ...

Isothermal Reactor for Continuous Flow Microwave-Assisted Chemical Reaction*

An isothermal reactor in which reaction solutions can be controlled at constant temperature under constant microwave irradiation was developed. This is useful for investigating microwave effects on chemical reactions that are not observed under conventional heating conditions. We devised a structure in which a heat-transfer medium with a low dielectric loss factor, which hardly absorbs any micr...

The Eschenmoser coupling reaction under continuous-flow conditions

The Eschenmoser coupling is a useful carbon-carbon bond forming reaction which has been used in various different synthesis strategies. The reaction proceeds smoothly if S-alkylated ternary thioamides or thiolactames are used. In the case of S-alkylated secondary thioamides or thiolactames, the Eschenmoser coupling needs prolonged reaction times and elevated temperatures to deliver valuable yie...

Optimization of Continuous Flow Adsorption of Heavy Metal Ions on Continuous System Column by Peganum Harmala Seeds

Background & Aims of the Study: Heavy metals discharge to environment is a worldwide problem growing in scale. When they accumulate in the environment and in food chains, they can profoundly disrupt biological processes. Peganum Harmala Seeds (PHS) was used as a bio-sorbent, using a continuous system for removing Pb2+, Co2+, Ni2+ and Cu2+ ions from aqueous solutions. ...
