Helicenes: The Photochemical Ring-Closure of Polymer-Supported 1,2-Diarylethylenes: Hexahelicene- and benzo[c]phenanthrene-2-carbaldehyde
Photolysis of a suspension (C6H6;I2) of 1-(4-formylphenyl)-2-(2-benzo[c]phenanthryl)ethylene and 1-(4-formylphenyl)-2-(2-naphthyl)ethylene anchored on a styrene-divinylbenzene copolymer (1a and 1b), followed by hydrolysis, yielded hexahelicene-2-carbaldehyde (2a) and benzo[c]phenanthrene-2-carbalde...
