Ti-catalyzed ring-opening alkynylation of epoxides with haloalkynes has been achieved, allowing an efficient and regioselective entry to various propargylic alcohols in moderate to good yields. The developed protocol features extremely mild reaction conditions, broad substrate scope, varied functional group compatibility, and chemospecificity in the rearrangements of epoxides to aldehydes.

A full account of a useful transformation from silylated 1,4-dili-thio-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 by applying our protocol. The structure of the α-lithio silole, which adopts a dimeric fashion through two lithium bridges, was confirmed by X-ray analysis. Furthermore, a possible mechanism of the skeleton rearrangements via E/Z isomerization of 1-silyl-1-lithio alkene and nucleophilic attack on silicon is proposed, and is also proved by experimental investigations. 2010 Wiley-VCH Verlag GmbH Co.

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 correspo
