Photochemical process of producing 3 5-di-substituted fuchsones |
| abstract |
IRRADIATION OF AN ACID-FREE ACETONE SOLUTION OF A 2,6DI(C1-8 SECONDARY OR TERTIARY ALKYL)PHENOL AND A BENZOPHENONE, WHICH CAN CHAVE PARA-SUBSTITUENTS, USING LIGHT HAVING A WAVELENGHT IN THE RANGE OF 300-500 MU PRODUCES A TRIPHENYL CARBINOL INTERMEDIATE. REPLACING THE ACETONE WITH ACIDIFIED METHANOL CONVERTS THE INTERMEDIATE TO A FUCHSONE WHOSE 3- AND 5-SUBSTITUENTS ARE THOSE OF THE PHENOL REACTANT AND ANY 4 - AND 4"-SUBSTITUENTS ARE THOSE OF THE BENZOPHENEONE REACTANT. THE FUSCHSONES ARE USEFUL AS DYES AND FOR THE MAKING OF BISPHENOLS. |
