The syntheses of the quinoxaline and pteridine proligands (3 and 4) related to molybdopterin are described and 3 has been characterised complexed via its dithiolene group to a CpCo(III) centre (5). Each of 3–5 has the sensitive hemiaminal unit of molybdopterin, unprotected, verifying its stability in vitro.
