钯催化硅烯从硅原子上带有二乙胺基的硅硼酯有效地转移到2-烯基吲哚，从而形成与吲哚环融合的1-硅-3-环戊烯环。在2-（1-烯基）吲哚反应中进一步进行硅烯转移，得到高收率的双硅化三环吲哚。
The palladium-catalyzed silylene transfer to 2-alkenylindoles from a silylboronic ester bearing a diethylamino group on the silicon atom takes place efficiently, resulting in the formation of a 1-sila-3-cyclopentene ring fused with the indole ring. Further silylene transfer proceeds in the reaction of 2-(1-alkenyl)indoles, giving bissilylated tricyclic indoles in high yields.
