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 and 3,5‐di‐ tert ‐butyl salicylaldehyde, and L1 /Ti(O i ‐Pr) 4 exhibited moderate to good activities to produce α‐acyloxyphosphonate. Furthermore, the performance difference of L1 and the traditional [ONO]‐type tridentate Schiff base L3 coordinating with Ti IV or Al III was also investigated.

In this work, BSEA-SBA-15 was prepared for the first time, which was prepared by covalently anchoring Schiff-base compound (N,N´-bis(salicylidene)ethylenediamine (BSEA) on SBA-15 by hydrothermal method. The structure and physicochemical properties were determined by elemental analysis, XRD, nitrogen adsorption–desorption, thermogravimetric analysis and FTIR spectroscopy, SEM, BET surface area and BJH pore size. The average pore diameter after the modification is 69A. It is expected that BSEA-SBA-15 can be used as an effective adsorbent for the removal of metal ions due to having porous structure and active functional groups.

The N,N′-bis(ferrocenylmethylene)ethylenediamine Schiff base was synthesized by condensing ferrocenylaldehyde with ethylenediamine. The complexes of the Schiff base with Zn(II), Co(II), Ni(II) and Fe(III) ions were synthesized. The compositions and properties of the ligand and its complexes were established by elemental analyses, IR, 1H NMR, UV-Vis. spectra and molar conductances.

Abstract The Schiff base is a special type of imine derivative formed by the condensation between a primary aromatic amine and an aldehyde or ketone, but sometimes the condensation products from aliphatic amine and ketone or aldehyde are also referred to as the Schiff bases. The prepared Schiff bases have wide application and are found to catalyze the highly enantioselective and diastereoselective reaction. Furthermore, some Schiff bases show antituberculous activity.

The syntheses of bis[TV, N' - ethylene - 2,2' - (phenylmethylene)bis(3,4 - dimethyl pyrrole - 5 -aldimino) ]monometallic complexes MH2L [M = Mn( II ) , Fe( III ) Cl, Cr(III) Cl, Cu( II ), Co( II ) , Ni( II ) , Zn ( II ) ] were first described . Their spectral characters and configurations were also discussed . The monometallic complexes were prepared by the reaction of ethylenediamine with another series of Schiff base mononuclear complexes, derived by the reaction of the appropriate metal salts with a Schiff base ligand. The Schiff base ligand was prepared from the [l + 2] condensation of ethylenediamine with 2,2'- (phenylmethylene)bis(3, 4 - dimethylpyrrole - 5 - carbox-aldehyde) .
