Photochemical interconversion of the two diastereoisomers cis- and trans-thianthrene dioxide (1) can be considered an example of photodynamic combinatorial chemistry (PDCC) in which the interconversion among diastereomeric equilibrating species is brought about by electromagnetic irradiation. Photoequilibrium can be shifted by irradiation at different wavelengths or by addition of SnCl2 that binds cis-1 more efficiently thantrans-1.

Abstract
Photochemical interconversion of the two diastereoisomers cis- and trans-thianthrene dioxide (1) can be considered an example of photodynamic combinatorial chemistry (PDCC) in which the interconversion among diastereomeric equilibrating species is brought about by electromagnetic irradiation. Photoequilibrium can be shifted by irradiation at different wavelengths or by addition of SnCl2 that binds cis-1 more efficiently thantrans-1.File in questo prodotto:
