Aza[6]helicene platinum complexes: chirality control of cis-trans isomerism.
نویسندگان
چکیده
It was serendipitously observed that cis-[PtCl2(NCEt)PPh3] reacted differently with either racemic or enantiopure 4-aza[6]helicene, giving respectively cis (racemic) and trans (enantiopure) [Pt(II)Cl2(4-aza[6]helicene)PPh3] complexes. This unexpected reactivity is explained through a dynamic process (crystallization-induced diastereoselective transformation) and enables a new aspect of reactivity in chiral transition-metal complexes to be addressed.

The binding energy and Thermodynamic Parameters of cis- Platinum Di Ammino Chlorine (cis-[Pt(NH3)2Cl]+) and trans- Platinum Di Ammino Chlorine (trans- [Pt(NH3)2Cl]+) complexes withGuanine has been studied by density functional theory (DFT) calculations in water. The bindingenergies (Ebin) of cis- and trans-[Pt(NH3)2ClG]+ are calculated to be 79.38 kcal/mol and 74.98kcal/mol, respectively. The b...

trans-Bis(alkynyl)palladium complexes, trans-[(PEt3)2Pd(-CtCC{dO}NR2)2] (NR2 = NMe2 (2a), N(CH2)4 (2b)), were synthesized by two different methods: (a) by copper-catalyzed reaction of HCtCC(dO)NR2with [PdCl2(PEt3)2] under basic conditions and (b) by treatingHCtCC(dO)NR2 with AgNO3 followed by transmetalation of the alkynyl ligand from silver to [PdCl2(PEt3)2]. The reaction of AgCtCC(dO)NMe2 (3a...
متن کاملCis-trans isomerism in a square-planar platinum(II) complex bearing bulky fluorinated phosphane ligands.
Transition-metal complexes bearing fluorinated phosphane and thiolate ligands has been an area of study in recent years and the chemical context of the current work is related to the metal-assisted functionalization of fluorinated derivatives. The cis and trans isomers of the square-planar complex bis[(pentafluorophenyl)diphenylphosphane-κP]bis(2,3,5,6-tetrafluorobenzenethiolato-κS)platinum(II)...

cis- and trans-Isomers of the platinum(II) nitrile complexes [PtCl2(NCR)2] (R = NMe2, N(C₅H10), Ph, CH2Ph) were examined as catalysts for hydrosilylation cross-linking of vinyl-terminated polydimethylsiloxane and trimethylsilyl-terminated poly(dimethylsiloxane-co-ethylhydrosiloxane) producing high quality silicone rubbers. Among the tested platinum species the cis-complexes are much more active...
متن کاملInduction of DNA-protein cross-links by platinum compounds.
The differences between cis- and trans-diamminedichloroplatinum II (DDP) in forming DNA-protein cross-links in isolated human lymphocytes were investigated. Both cis- and trans-DDP can induce DNA-protein cross-links. We show that cis-DDP forms complexes between DNA and proteins faster than trans-DDP. This results from an increase in the quantity of DNA and platinum together with an increase in ...
