Abstract
[reaction: see text] Silicon-bridged 1,6-diynes underwent [2 + 2 + 2] cycloaddition with alkynes in the presence of an iridium(I)-phosphine catalyst to afford densely substituted silafluorene derivatives. Extended silafluorene skeletons were constructed by the [2 + 2 + 2] cycloaddition of tetraynes.
摘要
[反应：见正文] 在铱（I）-膦催化剂存在下，硅桥连的1,6-二炔与炔烃发生[2 + 2 + 2]环加成反应，得到高度取代的硅芴衍生物。通过四炔的[2 + 2 + 2]环加成反应构建了扩展的硅芴骨架。
