and wide scope in aromatic and heteroaromatic chemistry are presented. Exchange of sulfur components surrounding arenes and heteroarenes may occur at 25 °C, in a process that one may call a “sulfur dance”. A dynamic covalent system involving four components illustrates the thermodynamically-driven formation of a thiacalix[2]arene[2]pyrimidine. This work stimulates the implementation of reversible SNAr
