A process for the preparation of a trichloromethyl-trifluoromethyl-benzene of the formula ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and represent hydrogen, fluorine or chlorine, By contacting at least one molecule of the formula ##STR2## wherein R.sup.1 and R.sup.2 are as previously identified, m and n are independently 0 to 3 With another molecule of the formula ##STR3## wherein M AND N ARE INDEPENDENTLY 0 TO 3 In the presence of a halogen transfer catalyst, optionally in the presence of a promoter.
一种制备三氯甲基-三氟甲基-苯的方法,其中R.sup.1和R.sup.2是相同或不同的,代表氢、氟或氯,通过使式子##STR2##中至少一个分子与另一个式子##STR3##中的分子接触,在卤素转移催化剂的存在下,可选地在促进剂的存在下进行。
