Comparative Example 1 and Experimental Examples 1 to 6. Effect of the equivalent of an activator relating to the present invention The same procedure as in Example 1 was carried out except for using TMSCl (5 equiv.) used in Example 1 in the various equivalents shown in the following Table 5, to obtain objective 4-methylphenyldiphenylsulfonium bromide. Yields of the obtained objective compound, triphenylsulfonium bromide (byproduct 1) and bis(4-methylphenyl)phenyl sulfonium bromide (byproduct 2) are shown in Table 5.
