Asymmetric arene-alkene cyclization reactions mediated by a chiral electrophilic organoselenium reagent afforded substituted carbocyclic derivatives with high diastereoselectivities. It was also found that [3-methoxyselenides are good precursors of seleniranium ions when treated with strong acids.

The iodine-magnesium exchange reaction with i-PrMgCl allows a mild preparation of functionalized arylmagnesium compounds bearing a leaving group in the molecule. With the appropriate transition-metal catalyst (a copper or cobalt salt), cyclization reactions occur leading to five-or six-membered ring
