摘要： The invention relates to an improved process for isomerizing polyunsaturated non-aromatic compounds including acyclic conjugated polyenes and alicyclic conjugated polyenes. In particular it relates to an improved and safe process for forming a 11-E retinoid compounds in high yield by expending as few energy as possible and with avoiding at most possible side products or product mixtures. This is achieved by feeding at least one of retinoid compounds of formula 2 to 5, or at least one of retinoid compounds of formula 2 to 5 and retinoid compound of formula 1, an organic solvent and a photosensitizer into a reaction device and irradiating the thus obtained reaction mixture with visible monochromatic light, at least 90 % of the power of said monochromatic light and at most 100 % of said power being emitted in the range from 460 nm to 580 nm.
