Process for producing cyanobenzoic acid derivatives
摘要
<p>A process for producing a cyanobenzoyl chloride compound represented by the following formula: <CHEM> wherein each of -COCl and -X represents a substituent of the benzene ring; the -COCl group is bonded to an m- or the p- position with respect to the CN group; X represents a chlorine atom or a fluorine atom; n is an integer between 0 and 4 inclusive; and when n is 2 or more the plurality of X's may be identical to or different from one another, which process comprises reacting a cyanobenzoic acid compound represented by the following formula: <CHEM> wherein -X represents a substituent of the benzene ring with phosgene or a precursor thereof.</p>
