The 1,3-dithiole-2-thiones or -selones ‌65‌ (Z = S, Se) are arylated by arenediazonium salts, where nitro-substituted arenediazonium salts react spontaneously, halo- and pseudohalo-substituted arenediazonium salts require copper(I) chloride as catalyst, and donor-substituted arenediazonium salts are unsuitable (‌Scheme 21‌).[‌172‌,‌173‌]
