New Thermo-Response Dyes: Coloration by the Claisen Rearrangement and Intramolecular Acid-Base Reaction
Applications in information storage and in thermally activated recording systems are anticipated for the novel allyl aryl ether 1. At 180°C 1 rearranges to phenol lactone 2, which in turn undergoes intramolecular proton migration to provide colored 3.
