Abstract: In this report, photochemical behavior of 2-(3-phenyl-trans-2-propenyloxy)benzophenone and 2-(3-phenyl -cis-2-propenyloxy)benzophenone is discussed. In contrast to allyl and propargyl ethers of 2-hydroxybenzophenone that were photoactive at 330 nm leading to the formation of 2,3-disubstitutedbenzofuranols, 2-(3-phenyl-trans-2-propenyl oxy)benzophenone and 2-(3-phenyl-cis-2-propenyloxy) benzophenone under these conditions led to photo somerisation and resulted in the formation of a mixture of cis and trans isomers in photo stationary equilibrium, due to intramolecular energy transfer.
Keywords: Photolysis, Hydroxy benzophenones, Triplet energy transfer, cis-trans somerisation.
