We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Since no chiral center exists in this molecule, its chirality is due to the dissymmetric orientation of substituents about a chiral axis (the axis defined by the three carbon atoms of the double bonds). Is it correct to use "the" before "materials used in making buildings are"? D3, (6m2) The syntheses and unique chemical properties of metalladithiolene rings (especially in [CpM(S 2 C 2 R 1 R 2)]-type complexes) found by our research group are reviewed.The constructions of metalladithiolene rings by one-pot reaction among [CpM(CO) n], alkyne, and elemental sulfur and by the reaction between [CpM(CO) n] and sulfur-containing heterocyclic compounds are Sulfoxide-CoA, with a sulfonyl and a methylene group replacing the carbonyl group and the sulfur atom of acetyl-CoA, was found to be a modest micromolar inhibitor of citrate synthase (11.1 M), indicating its potential as hydrogen bonding acceptor.
