Reduction of Epoxides, α,β‐Unsaturated Aldehydes, and Vicinal Diketones with “Reactive Titanocene”

The deoxygenation of epoxides 2 to give the alkenes 3 can be carried out with “reactive titanocene” stereoselectively in high yield. The reagent is generated in situ from 1. The other two title compounds allow access to bis(allyl alcohols) or bis(allyl) ethers and to acyloins, ketones, or vinylene carbonates.
