Abstract
The crystal of 5-phenyl-2-endo-(propane-2-sulfonyl)-bicyclo[2-2-1]hept-5-ene-2-carbonitrile1, a new radical-clock is described. The structure has confirmed the configuration for the positions of the phenyl and sulfonyl groups. In the crystal, the radical precursor carbon atom of the propane group is not neighbouring with the double bond of the norbornene. Nevertheless, in solution, it may be expected an ideal conformation with a short intergroup distance leading to a cyclization process. Crystal data: C17H19NO2S, triclinic, space group P−1,a=6.567 (3),b=10.407(5),c=12.610(6), α=110.48(2), β=95.88(2), λ=102.67(3).
