rates, i.e., , of trichloromethyl-bromo-addition reactions to fourteen p-Y-substituted phenylacetylenes (I-Y, with YF, Cl, Br, Me, t-Bu, OMe, SMe, SiMe3, CF3, CN, NO2, SOMe, COMe and CO2Me). The reaction was run in cyclohexane under nitrogen atmosphere at 65±0.5°C. All products were derived from the intermediate YC6H4CCHCCl3 adduct radicals. Correlation analysis of these rate data seems to suggest that
