Configurationally selective self-assembly of a cis-[3]pseudocatenane incorporating three tetrathiafulvalene units
Abstract
Dimacrocycle 6, incorporating three tetrathiafulvalene units, reacts with dication 7.2PF6 and dibromide 8 under ultra-high pressure (8 × 105 kPa), to exclusively give cis-[3]pseudocatenane 9.4PF6 in 20% yield.
