, p. 4291 - 4294 (2007/10/02)
A selective and mild photocatalytic procedure for benzylic oxydations with 9,10-dicyanoanthracene (DCA), an usual electron acceptor, in presence of methyl viologen (MV2+) and FeCl2 has been developped.Key words: Singlet Electron Transfer; benzylic oxidation; hydroperoxides

A selective and mild photochemical procedure for benzylic oxidations with 9,10-dicyanoanthracene (DCA) an usual electron acceptor, in the presence of methyl viologen (MV2+), an electron relay, has been developed.Methyl and methylene groups are oxidized in good to excellent yields to the corresponding hydroperoxides.
PHOTOOXYGENATIONS PAR TRANSFERT D'ELECTRON SENSIBILISEES PAR LE DICYANO-9,10 ANTHRACENE. ROLE DU SOLVANT ET FORMATION D'OXYGENE SINGULET.

, p. 2139 - 2142 (2007/10/02)
Photooxygenation of naphtalenic compounds sensitized by electron acceptors like 9,10 dicyanoanthracene (DCA) is shown to proceed by two distinct ways depending on the solvent polarity.In a polar solvent superoxide ion (O2-.) as well as singlet oxygen (1O2*) are involved while in a non polar solvent only singlet oxygen is produced.
