Synthesis of functionalized siloles from Si-tethered diynes
摘要:
A new synthetic itinerary to silole from Si-tethered diynes is reported. In this protocol, the Si-tethered diyne manifests definitely the reactivity of monoyne to form the lithio silole via zirconacyclopetadiene, 1,4-diiodo-1,3-butadiene, and the corresponding dilithiodiene successively. Lithio siloles thus obtained above could be easily functionalized to give various types of silole derivatives. Complex structure like bridged bis-silole compounds could also be constructed by this process. (C) 2009 Elsevier Ltd. All rights reserved.

A full account of a useful transformation from silylated 1,4‐dilithio‐1,3‐butadienes to α‐lithio siloles is described. These lithio siloles formed by this procedure are general, in terms of substitution patterns and synthetic methods, affording diversified silole derivatives. Notably, some structurally complex molecules, such as bridged bis‐silole compounds, have been synthesized easily and successfully
