investigated. The optimal conditions for selective preparation of mono- and diamino derivatives, which are ensured by the reaction temperature, were elucidated. In some examples of diamine synthesis, in order to improve the selectivity of second aminodefluorination, it is advisable to separate the isomeric monoamino derivatives produced in the first step of the synthesis.
polyhalogenbenzenes的Aminodefluorination(chloropentafluoro-,1,3-二氯四氟,符号-trichlorotrifluoro-,1,2,3,5-四氟和1,2,4,5-四氟-3- trifluoromethylbezenes)在无水氨的影响。阐明了由反应温度确保的选择性制备单和二氨基衍生物的最佳条件。在二胺合成的一些实例中,为了提高第二氨基脱氟的选择性,建议分离在合成的第一步中产生的异构单氨基衍生物。
