A process includes substituting a substituent on a substrate. The process includes reacting a salt of an anionic form of the substituent with an electrophilic fluorination agent to provide an electrophile containing a cationic form of the substituent. The electrophile is then electrophilically substituted on the substrate. In some aspects of the process, the substrate can be an aromatic or a non-aromatic. The process can be used for a variety of reactions having electrophilic mechanisms, including halogenation, thiocyanation and nitration.
一个过程包括在底物上替换一个取代基。该过程包括将取代基的阴离子形式的盐与亲电氟化剂反应,以提供含有取代基阳离子形式的亲电体。然后,将亲电体在底物上进行亲电取代。在该过程的某些方面,底物可以是芳香族或非芳香族。该过程可用于具有亲电机制的各种反应,包括卤代反应、硫氰化反应和硝化反应。
