Abstract

Abstract: Irradiation in the long-wavelength absorption bands of the P, y-unsaturated aldehydes 7, 8, and 9 in various solvents results exclusively in decarbonylation from the singlet excited state. Fluorescence and singlettriplet intersystem crossing have not been found to participate at the dissipation of excitation energy, The decarbonylation involves elimination of carbon monoxide and concurrent intramolecular transfer of the aldehydic ...
