The aminium salt induced reactions of stilbenes (la-d), affording a mixture of indane (2a--e) and/or tetrahydronaphthalene derivatives (3a,c,d), were found to occur with remarkably higher efficiency in 1,1,1,3,3,3hexafluoropropan-2-ol (HFP) than, if at all, in dichloromethane (DCM) solutions.

Spiro[1,2-dioxetane-3,1 0 -dihydroisobenzofuran] syn-3 bearing a hydroxy group at the 6-position (as a model syn-rotamer of parent dioxetane 4 bearing a 3-hydroxyphenyl group) and its isomer anti-3 (as a model anti-rotamer of 4) were synthesized. When these spiro-dioxetanes were treated with tetrabu
