Abstract Two bimetallic Fe(II)‐Cu(I) complexes, with tetrahedral Cu(I) center stabilized in a S2P2 environment, were synthesized and fully characterized using single crystal X‐ray diffraction, multinuclear NMR, IR UV‐Visible spectroscopy techniques. Density functional theory PBE0‐D3(BJ) was employed to elucidate the electronic features of these novel metal complexes. The computational analysis revealed that while all complexes adopted geometry gas phase shorter P−Cu(I) bonds than S−Cu(I) bonds. These cationic highly active catalytic cycloaddition reaction azides onto terminal alkynes. CuAAC carried out at room temperature as low 1 mg (0.1 mol %) catalyst loading deliver high yields corresponding 1,4 adducts 1,2,3‐triazoles water under aerobic conditions.

Abstract Two novel [ONS]‐type tridentate Schiff base ligands were prepared and employed in the acylphosphonylation of aldehyde. Ligand L1 was derived from 2‐amino‐3‐methylbutane‐1‐thiol 3,5‐di‐ tert ‐butyl salicylaldehyde, /Ti(O i ‐Pr) 4 exhibited moderate to good activities produce α‐acyloxyphosphonate. Furthermore, performance difference traditional [ONO]‐type L3 coordinating with Ti IV or Al III also investigated.
