Novel palladacycle N-heterocyclic carbene complexes with bidentate [C,N] and terdentate [C,N,N] and [C,N,O] Schiff bases. Synthesis, characterization and crystal structure analysis

Novel cis-[(NHC)1(NHC)2(L)Cl]platinum(ii) complexes – synthesis, structures, and anticancer activities

“…N-Methyl-and N-benzylimidazolium salts were prepared according to literature procedures (cf. ESI †), [22][23][24][25] as were 1,3-dimethyl-4-(3′,4′,5′-trimethoxyphenyl)-5-(4″-methoxyphenyl)imidazolium iodide 26 and complex 2a. 17 Complex 1b was prepared analogously to 1a 17 and is described in the ESI.…”

“…We prepared eight new cis-[Pt II (NHC) 1 (NHC) 2 Cl 2 ] complexes 5 with six different NHCs as ligands via DMSO precursor complexes 2. Since the two NHC ligands are introduced one at a time, complexes with two different NHCs can be synthesised starting from two different imidazolium salts 6 (ImH 1 ) and 7 (ImH 2 ) [22][23][24][25][26] (Scheme 2). We employed imidazolium chlorides that were 1,3-benzylated, or -alkylated.…”

A new azo‐Schiff base: Synthesis, characterization, biological activity and theoretical studies of its complexes

“…This is due to role of copper in preventing gastrointestinal damage by acidic anti-inflammatory agents. [19][20][21][22][23][24] There are limited studies of metal complexes of the Schiff base: 1H-indole-3-ethylene salicyldamine and its derivatives [25] and there are no data available regarding biological activities of these compounds. In this work, we have been interested in the design and synthesis azo-Schiff base prepared by reaction of m-hydroxy benzoic acid with (Schiff base B) of 3-[2-(1H-indol-3-yl)-ethylimino]-1.5-dimethyl-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylamine.…”

Synthesis of a dinuclear palladacycle with a doubly metallated ligand and its reactivity towards diphosphines

“…We have researched extensively terdentate [C,N,X] (X= O, N) ligands, but also bidentate [C,N] ligands, like imines [9]. In this line of research there have been studies of doubly cyclometallated compounds [10,11].…”
