<P>PROBLEM TO BE SOLVED: To provide O-acyl-N-aryl-N-(trifluoromethyl)hydroxylamine derivatives and a method for producing the same useful as production intermediates of medicines, pesticides and functional materials. <P>SOLUTION: In the method, the O-acyl-N-aryl-N-(trifluoromethyl)hydroxylamine derivatives represented by general formula (1) are produced by reacting nitrosobenzene derivatives, trialkyl(trifluoromethyl)silane and acid anhydride in the presence of a base. In the formula, R<SP POS="POST">1</SP>is a 1-7C acyl group; R<SP POS="POST">2</SP>is 1-6C alkyl group, a 1-6C alkoxy group, a 2-6C alkoxycarbonyl group, a nitro group, a cyano group or a halogen atom; n is an integer of 0-3; and a plurality of R<SP POS="POST">2</SP>may be the same or different when n is 2 or 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
