    摘要:A Convenient Synthesis Of Known And Unknown Isocyanates Of The Furan,Thiophene,And Mono-And Polyfluorophenyl Series,Involving Silylation Of Starting Amines With Hexamethyldisilazane Or Chlorotrimethylsilane,Followed By Phosgenation Of The Resulting N-Silyl-Substituted Amines. An Unusual High-Temperature Rearrangement Of 3-(Methoxycarbonyl)-4,5-Dimethylthiophene-2-Yl Isocyanate Into Its 5-Ethyl Isomer. Ortho-Fluorine Substituent In Anilines Decreases The Yield Of Isocyanates,Whereas 2,3,5,6-Tetrafluorophenyl Isocyanate Exists For Only A Short Time As A 5% Toluene Solution.
