3-substituted - 2 - trifluoromethylacryloyl fluorides and the process for their preparation
Abstract
Abstract DESCRIBED ARE SUBSTITUTED TRIFLUOROMETHYLACRYLOYL FLUORIDES HAVING A 3-SUBSTITUENT SELECTED FROM DIALKYLAMINO ARYLALKYLAMINO, ARYL, 5-MEMBERED RING AROMATIC HETEROCYCLICS HAVING AN ADDITION TO ONE OR MORE CARBON ATOMS THE FOLLOWING RING MEMBERS: OXYGEN, SULFUR, IMINO, ALKYLIMINO, OXYGEN AND UP TO 3 NITROGENS, SULFUR AND UP TO 3 NITROGENS, IMINO AND UP TO 3 NITROGENS, AND ALKYLIMINO AND UP TO 3 NITROGENS, BENZO-5-MEMBERED RING AROMATIC HETEROCYCLICS HAVING ADDITION TO ONE OR MORE CARBON ATOMS THE FOLLOWING RING MEMBERS: OXYGEN, SULFUR, IMINO, ALKYLIMINO, OXYGEN AND NITROGEN, SULFUR AND NITROGEN, IMINO AND NITROGEN, AND ALKYLIMINO AND NITROGEN. THE HETEROCYCLIC SUBSTITUENTS ARE BONDED TO THE TRIFLUOROMETHLYACRYLOYL FLUORIDE MOIETY BY A CARBON-CARBON BOND. THE CLAIMED PROCESS FOR THEIR PREPARATION COMPRISES THE REACTION OF A FORMYL-CONTAINING COMPOUND WITH PERFLUOROMETHACRYLYL FLUORIDE AT TEMPERATURES OF 0-200*C. 3-SUBSTITUTED-2-TRIFLUOROMETHYLACRYLOYL FLUORIDES ARE USEFUL AS TREATING AGENTS FOR PAPER PRODUCTS AND FABRICS.
