Abstract
The condensation of distal-dibromoresorcinarene 1 with formaldehyde and thi ols in acetic acid yields resorcinarenes 2, having thiomethyl and bromo sub stituents at the extraannular position in alternating sequence. This thiome thylation with the appropriate alpha,omega-dithiols leads to the intramolec ularly bridged derivatives 4, the thiacrown-resorcinarenes.
