A series of hydroxycyclopent-2-enones and methoxycyclopent-2-enones have been synthesized in a single operation from simple furan substrates using an innovative continuous flow nebulizer system (NebPhotOX). Photooxygenation of the furan substrates takes place in an aerosol within the NebPhotOX system.

A photoelectric conversion element includes a conductive support, a photoconductor layer including an electrolyte, a charge transfer layer including an electrolyte, and a counter electrode, in which the photoconductor layer has semiconductor fine particles carrying a metal complex dye represented by a specific formula.
Palladium-catalyzed cyclization of beta,gamma-acetylenic ketones gives furans by intramolecular oxypalladation and subsequent protodemetalation. 3-Allylfurans were exclusively obtained by trapping the intermediate 3-furyl-palladium species with allyl halides in the presence of 2,2-dimethyloxirane as a proton scavenger.
