Irradiation of 4-aryl-4-alkylhex-5-en-2-ones (e.g. ) or 5-aryl-4-alkylhex-5-en-2-ones (e.g. ) adsorbed on montmorilloniteK-10 in a commercial microwave oven furnishes the multialkylated naphthalenes (e.g. ).
Thermal activation of γ,δ-unsaturated ketones (1, 9 and 12) in the presence of a catalytic amount of propionic acid causes a rearrangement to give new γ,δ-unsaturated ketones (2, 10 and 14)via an intramolecular ene reaction followed by a retro-ene reaction.
