1-Phenylthiotricyclo[,7]heptane reacted with MeSO 2Br and BrCH2SO2Br directly at mixing at 20°C in CH2Cl2 along a ionic (electrophilic with respect to bromine) mechanism affording a product of an anti-stereoselective addition to the central bicyclobutane C1-C7 bond of the norpinane structure. The reaction product contains the exo-oriented sulfonyl group in the geminal position to the SPh substituent. The structure of the adduct with MeSO2Br in a single crystal was determined by XRD analysis. © Pleiades Publishing, Ltd., 2010. Source

A dimer of a monoradical was obtained proceeding from 1,3-bis(4,5- diphenylimidazol-2-yl)benzene and the rate constants were measured of the dissociation of dimers of 1,3-bis(4,5-diphenylimidazol-2-yl)benzene mono- and biradicals. © 2011 Pleiades Publishing, Ltd. Source
