corresponding 3-(polyfluorophenyl) prop-2-ynol derivative. Where R = N(CH3)2- and NH2- the acetylenic alcohol was not obtained; these were synthesized by the reaction of dimethylamine and ammonia with 3-(pentafluorophenyl)prop2-ynol itself. The acetylenic alcohols were converted to the corresponding polyfluorophenyl acetylenes by nickel peroxide in dioxan/aqueous NaOH. With benzene at 60° as solvent 3-(pent
由五氟和4-取代的四氟碘苯(取代基R为CF 3-,H-,CH 3-或CH 3 O-)与铜(I)3-(2'-四氢吡喃氧基)丙-1的反应已获得相应的3-(聚氟苯基)丙-2-炔醇衍生物。其中R = N(CH 3)2-和NH 2-未获得炔属醇;这些是通过二甲胺和氨与3-(五氟苯基)丙-2-炔醇本身的反应合成的。通过在二恶烷/ NaOH水溶液中的过氧化镍将炔醇转化为相应的多氟苯基乙炔。用60℃的苯作为溶剂,将3-(五氟苯基)丙-2-炔醇氧化成醛和酸,在回流的苯中,得到1-4双(多氟苯基)丁二炔和多氟苯基乙炔。已经讨论了一些反应的机理。
