Treatment of α-chloro-α,α-difluorotoluene and α-chloro-α,α-difluoroanisole with chlorotrimethylsilane in the presence of magnesium in DMF led to their corresponding trimethylsilyl derivatives. These compounds are able to transfer their fluorinated group to various electrophilic substrates (carbonyl compounds, disulfides, phenyl isocyanate).
在 DMF 中,在镁的存在下,用三甲基氯硅烷处理δ-氯δ,δ-二氟甲苯和δ-氯δ,δ-二氟苯甲醚,可得到相应的三甲基硅烷衍生物。这些化合物能够将其氟化基转移到各种亲电基质(羰基化合物、二硫化物、苯基异氰酸酯)上。
