Method for photochemical isomerization of organic compounds under the influence of a photosensitizer.

摘要

The invention relates to a method for isomerizing photochemistry ORGANIC COMPOUNDS, ESPECIALLY FOR CONVERSION photochemistry COMPOUNDS tachysterol compounds previtamin DY COMPOUNDS OF TRANS-VITAMIN D COMPOUNDS CIS-VITAMIN D UNDER THE INFLUENCE OF RADIATION, EXPOSING A solution of the organic compound WILL BECOME THE PRESENCE OF A NON-POLYMERIC photosensitizer to light with a wavelength between 300-1000 NM APPROXIMATE and then isolating the resulting product, wherein used as photosensitizer derivative substituted thiophene with substantial absorption in the WAVELENGTH. The invention also relates to a new photosensitizer used in the isomerization reaction
