The preparation of a number of novel aromatic macrocycles related to porphins, but containing furan and thiophenrings in addition to pyrrole rings, is described, together with deuterium exchange studies on some of the macrocycles.

Rational syntheses are described of a number of new 22 π-electron macrocycles containing pyrrole, furan, and thiophen rings and one or two direct links. A further example of the sulphurextrusion process applied to macrocycle synthesis is provided. N.m.r. studies are used to show that all the macrocycles are aromatic, and they all contain intense Soret type bands in their visible spectra. The dioxasapphyrin
