摘要
The reaction of tetrabutylammonium triphenyldifluorosilicate with 2,4-dinitro(trifluoromethoxy) benzene, in acetonitrile and under microwave irradiation, generates a trifluoromethoxide anion which is able to substitute activated bromides (benzyl bromide, cinnamyl bromide), as well as, to some extent, alkyl iodides. Aliphatic trifluoromethyl ethers are thus formed. This is the first example of the nucleophilic displacement of the trifluoromethoxy group from an activated aromatic ring.
