Maleic anhydride–benzene and maleic anhydride–acetone molecular complexes
Abstract
Concentration- and temperature-dependent n.m.r. chemical shifts, and concentration-dependent heats of dilution and solution, for maleic anhydride in acetone or benzene, are interpreted in terms of equilibria between monomers and solvent–solute molecular complexes, and these complexes are presumed to be involved in photocycloaddition reactions.
