Synthesis and characterisation of some mixed ligand complexes of thallium (i) metal with isonitrosoethylmethyl ketone

The present investigation has been undertaken to examine complex formation by thallium (I) derivatives of 2-nitro phenol (ONP), 2,4-dinitrophenol (DNP), 2,4,6-trinitrophenol (TNP), 1-nitroso-2-naphthol (1N2N), 8-hydroxyquinoline (8HQ), and 2-aminobenzoic acid (OABA) with Isonitrosoethylmethyl Ketone. They have general formula [ML (HL′)], where M = Tl (I), L = deprotonated ONP, DNP, TNP, 8-HQ, 1N2N and OABA and L′ = Isonitrosoethylmethyl Ketone. Isonitrosoethylmethyl Ketone is ambidentate ligand and can donate through oxygen or nitrogen or both. The preparation of mixed ligand complex with the thallium (I) salt of 2,4-dinitrophenol and 2,4,6-trinitrophenol with the Isonitrosoethylmethyl Ketone (INEMK) have very low yield.

Mild Temperature Copper-Catalyzed Amination of Aryl Halides with Aqueous Ammonia in the Presence of Pyridyldiketone Ligands

Ambidentate ligand pyridyldiketones were used in combination with copper to catalyze maintain of aryl halides under very mild temperatures. This novel catalytic system allow efficient coupling in one of the smoothest conditions ever reported in literature.

1,2,3-Triazole based bisphosphine, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)-phenyl)-4-phenyl-1H-1,2,3-triazole: an ambidentate ligand with switchable coordination modes

This paper describes the synthesis of a triazole based bisphosphine and its transition metal chemistry and catalytic utility in Cu-free Sonogashira alkynylation/cyclization reaction.

Bridging cyanides from cyanoiron metalloligands to redox-active dinitrosyl iron units

Cyanide, as an ambidentate ligand, plays a pivotal role in providing a simple diatomic building-block motif, for controlled metal aggregation, M–CN–M′.
