The synthesis reported here of the shape-persistent macrocycle 9 with two opposing terpyridine units, and with pendant flexible chains for solubility reasons, was achieved by Suzuki cross-coupling of two 'half-cycles', the bisboronic acid ester 7 and its diiodo counterpart 8. Cycle 9 was obtained on a 100 mg scale in a yield of 20%. It was characterized by FAB mass spectrometry and 1H and 13C NMR spectroscopy. Cycle 9 is the first shape-persistent cycle containing terpyridine units that is larger than cyclosexipyridine. An improved synthesis of the important building block dibromoterpyridine 12 is also presented.

The 330 mg to 12 g scale synthesis of a variety of arylene (3,5-8) and hetarylene building blocks with bipyridine (16,17,19) and terpyridine units (21-23,25) by and for transition metal-mediated cross-coupling reactions is reported. All these compounds ca
