- ... A macrocyclic ligand (L⁴–) comprising two pyridine(dicarboxamide) donors was used to target reactive copper species relevant to proposed intermediates in catalytic hydrocarbon oxidations by particulate methane monooxygenase and heterogeneous zeolite systems. Treatment of LH₄ with base and Cu(OAc)₂·H₂O yielded (Me₄N)₂[L₂Cu₄(μ₄-O)] (1) or (Me₄N)[LCu₂(μ-OH)] (2), depending on conditions. Complex 2 wa ...
