Synthesis of (η5 -cyclopentadienyl)-1-(4-benzyloxycarbonyl-3,4-dihydroquinoxalin-2-yl )et hene-1,2-dithiolatocobalt(III) and (η5-cyclopentadienyl)-1-[2-(N, N -dimethylaminomethyleneamino)-3-methyl-4-oxopteridin-6-yl]ethene-1,2 -di thiolatocobalt(III)

Abstract

Cobalt(III) complexes are reported in which (a) a dihydroquinoxalinylethenedithiolate ligand models the pyrazine ring oxidation level in Moco, and (b) a pteridinylethenedithiolate models the pteridine ligand in Moco.
