摘要:Processes for the synthesis of phthalides and fluorans are disclosed. New isolatable intermediate phthalides have been found which serve as precursors to the production of fluorans. The products of this invention are synthesized from keto acids and phenolic amines, wherein the mole ratio of the keto acids to the phenolic amines is in excess of 1:1. Not only is product yield greatly improved, but usual condensation times of 24 hours and longer have been reduced to about 5 hours.
