A method for producing halogenphenoxyfettsaeurederivaten by selective halogenation and halogenphenoxyfettsaeurederivate

摘要

the present invention provides a procedure for the manufacture of the formula (i) are halogenphenoxyfettsu00e4urederivates: $f1 (wherein r, r1, r2, x, and y are defined as in the description), which is the selective halogenieren a by the following formula (ii). en phenoxyfettsu00e4ure in the presence of a halogenierungsmittels includes: $f2 (wherein r, r1,r2 and x are defined as in the description.) $a the present invention is also new in the formula (i) above halogenphenoxyfettsu00e4urederivate: $f3 wherein r ', r1', r2 ', x' and y 'are defined as in the description.$a by the procedure of the present invention halogenphenoxyfettsu00e4urederivate received as intermediate for herbicides and other useful.
