Abstract

Photochemically or thermally initiated reactions of arenesulfonylethynyl(trimethyl)silanes ArSO₂C≡CSiMe₃ (Ar = Ph, 4-MeC₆H₄) with 1-R-tricyclo[4.1.0.0^2,7]heptanes (R = H, Me, Ph) involve addition to the C¹–C⁷ central bicyclobutane bond of the latter with the formation of bicyclo[3.1.1]heptane (norpinane) derivatives with endo(anti)-oriented arenesulfonyl group. A plausible reaction mechanism is discussed.
