The presented experimental work investigates the usefulness of temporary monoprotection of symmetrical terminal diynes in the coupling with aryl iodides. The monoprotection/cross-coupling/deprotection approach proved to be efficient for the coupling of diynes with aryl substrates avoiding the formation of diarylated byproducts. The high importance of the ratio of solvents in the Sonogashira coupling
提出的实验工作研究了在与芳基碘化物偶联中对称末端二炔的暂时单保护的有用性。单保护/交叉偶联/去保护方法被证明对于二炔与芳基底物的偶联是有效的,避免了二芳基化副产物的形成。证明了在Sonogashira偶联中溶剂比例的重要性。
