A modular one-pot synthesis yielding tetracoordinated-N,N,N,N-copper(I) complexes bearing imine and diimine ligands was developed. Copper aids the condensation of a pyridine or imidazole carbaldehyde with a biphenyl amine and even stabilizes labile ligands. Tetradentate and bidentate ligands were formed, the latter forming homoleptic CuL2 complexes. The identity and purity of the compounds were assessed by NMR, elemental analysis and mass spectrometry. The interconversion of different species in solution was studied by variable temperature NMR. The complexes aim to mimic the histidine copper brace of lytic polysaccharide monooxygenases (LPMOs) and bond lengths obtained from XAS and single crystal XRD for the complexes were compared to reported photoreduced LPMOs.

AbstractSeveral ways to functionalize hydroxy-tripod-ligands (HOCH2C(CH2PR2)3) by activation with electrophiles are presented. The use of carboxylic halides and anhydrides is shown to be generally successful for esterification reactions in a one-pot synthesis starting from the oxetanes O(CH2)2C(CH2PR2)2. Facial coordinaton of the related esters towards iron(II) and molybdenum(O) can be achieved depending on the nature of the phosphane donor groups. If methyliodide or trimethylsilylchloride are used as electrophiles in order to functionalize the hydroxy group in HOCH2C(CH2PR2)3, it is necessary to proctect the phosphane groups by formation of the tris-borane adduct. All new compounds have been fully characterized by the usual analytical techniques as well as by X-ray analyses on selected examples.
