Molecular recognition of an adenine derivative by organoplatinum(II) complexes with hydrogen-bonding functionality

Abstract

The first examples of adenine binding by isomeric organoplatinum(II) complexes bearing Hbonding nicotinic and isonicotinic acid ligands are reported. Notably, a subtle switching of the H-bonding functionality from the 3-to 4-position of the pyridyl ring leads to a significant change in both the strength of association and the site of adenine binding.

Supramolecular organometallic chemistry: the platinum(iv) paradigm

“…4. [28][29][30] Because the ligand is unsymmetrical, the oxidative addition of a reagent RCH 2 Br to the dimethylplatinum(II) complex [PtMe 2 (L1)], 45, gives the corresponding chiral platinum(IV) product [PtBrMe 2 (CH 2 R) (L1)] as a mixture of enantiomers (C = clockwise; A = anticlockwise). The ligand L1 is planar and its complexes often exhibit supramolecular association by π-stacking as well as by hydrogen bonding, and this often leads to poor solubility of the complexes.…”

Novel arylplatinum complexes with 2,2′‐dimethyl‐4,4′‐bithiazole: Synthesis, characterization, single crystal structure determination, and investigation of CT‐DNA interaction

“…Recently, the synthesis of some organoplatinum complexes with different ligands and geometries has been reported. [5,11,13,22,[32][33][34][35][36][37][38][39][40][41][42] In this contribution, we report the synthesis of novel heteroleptic platinum complexes containing di-aryl and dm4bt. Characterizations of these complexes are done by different methods like ultravioletvisible (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance ( 1 H NMR), elemental analysis, and conductivity.…”
