High throughput screening (HTS) of a 205 member Schiff base salicylaldimine ligand library derived from salicylaldehydes bearing bulky ortho-substituents, i.e., 9-anthracenyl, 1,4,5,8-tetramethylanthracenyl or triptycenyl, reacted in-situ with (p-tolyl)CrCl2(thf)3, identified two new classes of highly active chromium based systems for the oligomerization and polymerization of ethylene, respecti...

The reaction of cis-[PtCl₂(dmso)] with the salicylaldimine ligand, N-(2-hydroxybenzylidene)-2,6-di-isopropylaniline, LA in the presence of sodium acetate in methanol produced both cis- and trans-[PtClLA(dmso)], 1a and 1b. An analogous reaction for the less bulky ligand, N-(2-hydroxybenzylidene)aniline LB produced only cis-[PtClLB(dmso)], 2. The reactions of these dmso complexes with triphenylph...

A series of trans-Pt(II)(salicylaldimine)(4-picoline)Cl complexes were synthesized in 78-87% yield using a one-pot procedure from commercially available precursors. The structures of these complexes were characterized by (1)H, (19)F and (13)C NMR spectroscopy, HRMS (ESI) as well as single crystal X-ray analysis. Bioactivity investigations including bio-assay, time- and dose-dependent, cell cycl...

Several derivatives and analogs of the recently reported antiproliferative and antitumor agent trans-bis(salicylaldoximato)copper(II) (CuSAO2) have been prepared and tested for antiproliferative activity against L1210 leukemia cells in vitro. The salicylaldimine analog of CuSAO2 had a very strong antiproliferative activity, the 2-day IC50 value being lower than 3 micrograms/ml. The 2,3-dihydrox...

5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladiminato]copper(ii) [alkoxy=oncnh2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and ir spectra. all complex homologues are thermally stable. cyclic voltammetric studies indicated that all copper...
