- 中文摘要: The solvolysis of 1-tert-butyl-1-(4-phenoxy)methyl bromide (5b) and chloride (5c) in a variety of solvents were carried out. Limiting SN1 mechanisms were suggested from the observation of linear relationships using single-parameter Winstein-Grunwald type correlation between logarithm of rate constants with YxBnBr and YxBnCl scales, respectively. This result indicated positive charge delocalization over both aryl rings and provided further evidence for possible contribution of non-canonical resonance structure in the cationic transition state.
