efficient strategy toward conjugated arylbuta-1,3-diynyl sulfides (Ar–C≡C–C≡C–SR) was herein reported. In the newly developed one-pot, three-steps protocol, the synthetically or materially significant arylbuta-1,3-diynyl sulfides were obtained from easily accessible 4-hydrocarbylthio-1-arylbuta-1,3-diones, avoiding usage of expensive terminal aryl acetylenes as substrates or any transition metal complexes
本文报道了一种针对共轭芳基丁胺-1,3-二炔基硫化物(Ar-C≡C-C≡C-SR)的有效策略。在新开发的一锅三步方案中,从易于获得的 4-hydrocarbylthio-1-arylbuta-1,3-dioones 中获得了具有合成或物质意义的 arylbuta-1,3-diynyl sulfides,避免使用昂贵的终端芳基乙炔作为底物或任何过渡金属配合物作为催化剂。具有可接受产率的有效方法的克级实验提供了工业利益的良好替代方案。
