The photochemical [3 + 2]cycloaddition reaction of 2,2,3,3-tetra-arylthiiranes and tetracyanoethylene through electron donor–acceptor complexes
Abstract
Upon irradiation of the electron donor–acceptor complexes of 2,2,3,3-tetra-arylthiiranes and tetracyanoethylene (TCNE), the [3 + 2]cycloadditions occurred efficiently without the desulphurisation of thiiranes.
