Catalytic synthesis of flavanone without stirring or heating

Abstract

We developed a new approach for the synthesis of flavanone from chalcones without electrical energy, such as stirring or heating, by using a cesium fluoride–crown ether complex. This “zero electrical energy reaction” is a new category of reaction that has the potential to replace the general organic reaction.
