Microwave-assisted solvent-free instantaneous Claisen rearrangement for synthesis of bis(3-allyl-4-hydroxyphenyl) sulfone

Abstract

Solvent-free Claisen rearrangement of bis(4-allyloxyphenyl) sulfone (1) under microwave irradiation for 5 min gave high yields of bis(3-allyl-4-hydroxyphenyl) sulfone (3), which has been synthesized up to now under conventional heating for 2–30 h as a color developer for a heat- or pressure-sensitive recording in industry.
