                                    The photochemistry of the 'central methane'-substituted 3-benzyl-2(5H)-furanone system (1) is described. Despite its di-pi-methane structure, photochemical arylation was found to predominate in place of the di-pi-methane rearrangement, and gave substituted tetrahydroindenofuranones (2) in good yields.
