Carbocycle Formation via Intramolecular Insertion of Alkynes into Titanium-Carbon Bonds

Treatment of alkyl titanocene chloride complexes with the Lewis acids EtAlCl2 or Me2AlCl resulted in intramolecular insertion of a tethered alkyne into the Ti-C bond.Regioselective alkyne insertion produced exocyclic trisubstituted alkene products resulting from four-, five-, and six-membered ring formation.In the case of cyclohexane formation, the alkyne was found to insert with syn stereoselectivity.

A heterogenized palladium acetate catalyst, in the presence of oxygen and perchloric acid in ethanol-water caused the direct conversion of terminal and internal monoalkenes into the corresponding alkynes, under mild conditions and in high yields; Wacker-type ketonization occurs with the same reagents in dioxane-water.
