硅桥联的 1,6-二炔在铱 (I)-膦催化剂存在下与炔烃进行 [2 + 2 + 2] 环加成，得到密集取代的硅芴衍生物。通过四炔的[2+2+2]环加成构建了延伸的硅芴骨架。
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.
