METHOD FOR PRODUCING 3,3"-DIALLYL-4,4'-DIHYDROXYDIPHENYL SULFONE

Document Type and Number:

Japanese Patent JP2005075757

Kind Code:

A

Abstract:

To provide a method for producing 3,3'-diallyl-4,4'-dihydroxydiphenyl sulfone useful as a developer for a thermosensitive recording material in a short reaction time in an excellent yield.

The method for producing 3,3'-diallyl-4,4'-dihydroxydiphenyl sulfone comprises subjecting 4,4'-diallyloxydiphenyl sulfone to rearrangement reaction in the presence of a chelating agent, preferably in the coexistence of an antioxidant, substantially in the absence of oxygen at 150-350°C, more preferably under microwave irradiation.
