A Cationic Sigmatropic Rearrangement
Nishizawa, Mugio,Noyori, Ryoji
, p. 2233 - 2234 (1981)
The first example of the cationic sigmatropic reaction has been achieved by the reaction of 1,3-dibromo-3-methyl-6-hepten-2-one and diiron nonacarbonyl.

Treatment of appropriately substituted Se-phenyl 5,9,13-triene- and 5,9,13,17-tetraene-selenoates, i.e. 9b, 33, 40, 47a and 47b, with Bu3SnH-AIBN is found to lead to angular six-ring fused polycycles, viz. 20, 34, 50, 53 and 54 respectively, via consecuti

Cyclobutylcarbinyl alcohols of the bicyclo left bracket 3. 2. 0 right bracket heptane ring system are produced by UV irradiation of alpha -, beta -, and gamma -alkenylallyl alcohols in the presence of copper (I) trifluoromethanesulfonate (CuOTf). endo-2-Hydroxy epimers of bicyclo left bracket 3. 2. 0 right bracket heptan-2-ols are generated stereoselectively. This result as well as the effect of CuOTf on the **1H NMR spectrum of 4,4-dimethyl-1,6-heptadien-3-ol suggests that coordination of two C equals C bonds and the hydroxyl group with a single copper (I) is important. The derived bicyclo left bracket 3. 2. 0 right bracket heptan 2-ones fragment cleanly at 580 degree C to afford cyclopent-2-en-1-ones. Geometric isomerization competes with photobicyclization of (E)- and (Z)-octa-2,7-dien-1-ols.
