Iron pentacarbonyl is an effective promoter for additions of halogenated acid esters and nitriles to pentafluorophenyl carbonyl compounds 1, 4, and 5 by the Reformatsky-type reaction and reductive coupling of compound 1. The electron-withdrawing character of the pentafluorophenyl group has a significant effect on the reaction pathway and the type of the reaction products. The reactions involving metal

Co2(CO)6(C6F5·C⋮C·C6F 5), shown by its chemical and spectroscopic properties to be similar in structure to its hydrocarbon analogue; octafluoro-4,4′-dimethoxytolan behaves similarly. Tetrakispentafluorophenylcyclopentadienone (perfluorotetracyclone) is obtained when a solution of the cobalt carbonyl complex of decafluorotolan is heated. Reaction of decafluorotolan with iron penta- or dodeca-carbonyl yields a complex
二碘乙炔和五氟苯基溴化镁以良好的收率得到十氟甲苯磺酸(C 6 F 5 ·C⋮C·C 6 F 5)。托兰中的三键容易进行催化氢化,添加溴和氧化裂解,但对水合,碘化和羰基化反应相对较弱。十氟甲苯磺酸在4和4'位置与甲醇离子反应,并在用硫加热时,四苯并五氟苯基噻吩的收率很高。甲苯胺与八羰基钴反应生成络合物Co 2(CO)6(C 6 F 5 ·C⋮C·C 6 F 5),其化学和光谱性质表明其结构与烃类似物相似;八氟-4,4'-二甲氧基tolan的行为类似。加热十氟托伦的羰基钴络合物溶液,可得到四氟五氟苯基环戊二烯酮(全氟四环酮)。十氟托伦与五羰基铁或十二羰基铁反应生成复合物Fe 2(CO)6(C 6 F 5 ·C⋮C·C 6 F 5)2,以及全氟四环酮。
