A diol-functionalized ionic liquid: an efficient, simple, and recoverable 'capture and release' reagent for aldehydes

摘要

A new diol-functionalized ionic liquid, 2,2-bis( 1 -(1 -methyhmidazohum)methylpropane-1,3-diol hexa-fluorophosphate, was synthesized and applied as a facile, efficient, and recoverable "capture and release" reagent for aldehydes. This method has the advantages of homogeneous reaction, heterogeneous separation, and recyclable uses.
