Abstract
A green, high rate, high yielding, and selective Appel reaction that make use of 1,3-dihalo-5,5-dimethylhydantoins and N-halo-succinimides as halogenation reagents. The new Appel reaction method was developed for batch and continuous flow reactors.

Abstract
AbstractOscillatory flow reactors (OFRs) superimpose an oscillatory flow to the net movement through a flow reactor. OFRs have been engineered to enable improved mixing, excellent heat- and mass transfer and good plug flow character under a broad range of operating conditions. Such features render these reactors appealing, since they are suitable for reactions that require long residence times, improved mass transfer (such as in biphasic liquid-liquid systems) or to homogeneously suspend solid particles. Various OFR configurations, offering specific features, have been developed over the past two decades, with significant progress still being made. This review outlines the principles and recent advances in OFR technology and overviews the synthetic applications of OFRs for liquid-liquid and solid-liquid biphasic systems.
