Figure 3: Self-assembly and capture of a known cyclophane.
From: A facile route to old and new cyclophanes via self-assembly and capture
(a) Self-assembly of H3L3 (1 mol SbCl3, 1.2 mol I2; 69%) followed by capture (95%) by sulfur extrusion with HMPT (4 mol) provides known trithiacyclophane 3 in overall 65% yield. (b) A traditional stepwise route to 3 proceeds in 5% yield.
