Intramolecular cyclization of tert-butyldiphenylallylsilane units and carbonyl groups: allylsilane terminated cyclization versus the ene reaction

Research has been conducted on the tert-butyldiphenylallylsilane. The reaction of this compounds with allene producing allylsilane-vinylcopper intermediate has been carried out and the results indicate that upon treatment with alpha,beta-unsaturated ketones the reaction leads to the allylsilane containing ketones.
