摘要

Abstract Substitutions on [(pentafluorophenyl) ethynyl] trimethylsilane (1) with nucleophiles, Nu-X (2) give the corresponding [(p-substituted-tetrafluorophenyl) ethynyl] trimethylsilanes (3) or (p-substituted-tetrafluorophenyl) ethynes (4). The trimethylsilyl group of (3) can be easily removed by treatment with dilute alkali to give [(p-substituted-tetrafluorophenyl) ethynes (4). Diacetylenes containing fluoro-aromatic rings are prepared by the ...
