Thermal or photochemical reactions of phenyliodonium bis(arylsulphonyl)methylides with alkenes lead normally to gem-(arylsulphonyl)cyclopropanes. Norbornene and trans-stilbene, however, afford 1-(phenylsulphonyl)indane derivatives. The crystal structure of the title compound {R= 0.038 for 3 468 unique observed reflections [I/σ(I) 3.0]} confirmed the identity of the product with norbornene. Diarylacetylenes give 1-(arylsulphonyl)indenes. Thermal decomposition of the glides involves a new rearrangement, with formation of aryl arenethiosulphonates.
