Abstract
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 Chodkiewiez-Cadiot and the Hay coupling of the corresponding terminal acetylenes (4) .
