PROCESS FOR THE PREPARATION OF FLUORINATED KETONES |
| abstract |
An industrially useful process is provided by which fluorinated ketones having various structures can be prepared in shorter steps. That is, a process for the preparation of fluorinated ketones of the general formula (5) which comprises reacting a compound (3) having a fluorine content of 30 % by mass or above with fluorine in a liquid phase to obtain a compound (4) and subjecting the compound (4) to decomposition of ester linkage: R?CCOOCHRARB (3) RCFCOOCFRAFRBF (4) RAFRBF¿C=O (5) wherein R?A and RB¿ are each a monovalent organic group such as alkyl, or R?A and RB¿ may be united to form a divalent organic group such as alkylene; R?AF and RBF¿ are monovalent organic groups derived from R?A and RB¿ respectively by fluorination, e.g., perfluoroalkyl, or R?AF and RBF¿ may be united to form a divalent organic group such as perfluoroalkylene; and R?C and RCF¿ are each a monovalent organic group optionally containing an etheric oxygen atom, e.g., perfluoroalkyl. |
