Synthesis of photochromic 2,3-bis(2,5-dimethyl-3-thienyl)-3-cyanoacrylates by the Beckmann rearrangement of a cyclobutenedione derivative
摘要:
An unusual Beckmann rearrangement was discovered in the reaction of 3,4-bis(2,5-dimethyl-3-thienyl)cyclobut-3-ene-1,2-dione with hydroxylamine hydrochloride to give esters of 2,3-bis(2,5-dimethyl-3-thienyl)-3-cyanoacrylic acid.
