The number of sulfo-group affects the degree of sensibilization, and their relative position has not the influence basically. 试剂中磺酸基的数目影响其增感程度,而其相对位置基本上无影响。
Ten sulfo-group containing compound were tested whether they could be used as the phase transfer catalyst ( PT CS) for the electrophilic substitution in the solution of H2O/ CH3COONa-CH3COOH/ ClCH2Cl by measuring the coupling reaction rate constant. 选择了10个含磺酸基团的化合物作为相转移催化剂,测定其在H2O/CH2COOH-CH3COONa/ClCH2Cl体系中的亲电偶合反应速率常数。
