Abstract
Through their first excited singlet states, cyanothiophens undergo phototranspositions for which permutation pattern analysis and the isolation of furan–thiabicyclopentene adducts from irradiations in furan suggest a mechanism involving 2,5-bonding followed by a ‘walk’ of the sulphur atom.Keywords
