Synthesis and characterization of new neutral Mn(I) tricarbonyl complexes with 8‐hydroxyquinoline and imidazole ligands as CO releasing molecules

A series of manganese(I) tricarbonyl complexes formulated as [Mn(8-HQ)(CO)3Imd] (HQ = hydroxyquinoline and Imd imidazole derivatives) was synthesized fully characterized. These structures could be easily accessed from a common dimeric edifice [Mn2(8-HQ)2(CO)6]. The structure this complex has been confirmed by X-ray diffraction studies. Its reaction with range derivatives (Imd) yielded the monomeric [Mn(8-hydroxyquinoline)(CO)3Imd] various functional groups an anchoring point for vector. Photoactivation all these blue-light irradiation led to liberation 3 mol CO per determined experimentally. Spectroscopic computational methods were employed explore mechanism release. Finally, manganese including more elaborate ligand N- C-di-protected histidine successfully synthesized, opening way its direct incorporation in peptides.
