Kinetic and mechanistic studies of cisplatin analogues bearing 2,2?-dipyridylalkylamine ligands

A series of mononuclear Pt(II) complexes of the type diaqua(2,2?-dipyridylalkylamine)platinum(II) (where the alkyl group = methyl, ethyl, propyl, butyl or hexyl) were synthesized to investigate their nucleophilic substitution behaviour and the influence of the alkyl chain bonded to the tertiary nitrogen atom joining the two pyridine rings on the reactivity of the chosen complexes. The trend in rate constant shows that introduction of the sigma-donating alkyl chain on the tertiary nitrogen joining the two pyridine moieties reduces the pi-acceptor ability of the cis coordinated pyridine rings resulting in a less reactive Pt(II) centre which causes a decrease in the reaction rate. This is well supported by data from DFT calculations. It is also evident that the alkyl chain also introduces a steric effect which blocks the approach of the nucleophile to the Pt(II) centre. The boat-like structure of the six-membered chelate ring also contributes to the steric effect. The study has also shown that two substitution processes going through an associative mode of activation are observed. The first is the simultaneous substitution of the two aqua ligands, and the second is due to the dechelation of the ligand, an indication of possible disintegration of the complex if used as a drug. Graphical Abstract: The substitution reactions of cisplatin analogues and bio-relevant thiourea nucleophiles follow two-step associative processes with the last step encountering a complete dechelation of the ligand.[Figure not available: see fulltext.]

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C12H22O11, you can also check out more blogs about499-40-1

The use of 2-deoxy-2-trichloroacetamido-D-glucopyranose derivatives in syntheses of oligosaccharides

3,4,6-Tri-O-acetyl-2-deoxy-2-trichloroacetamido-alpha-D-glucopyranosyl trichloroacetimidate and its O-benzylated analogue were tested as glycosyl donors in the reaction with a set of sugar acceptors unsubstituted on O-3 and O-4, typically encountered in the synthesis of oligosaccharides.Glycosides were obtained in good to excellent yields with only a slight excess (1.1-1.2 equiv) of the donor, and with a high degree of 1,2-trans stereoselectivity.The corresponding 2-(trichloromethyl)oxazolinium ion was postulated to be the major reactive intermediate.The N-trichloroacetyl groups in the disaccharide products were easily transformed into N-acetyl under neutral conditions by reduction with tributylstannane.

Polylactides with aldaric ester end groups or chain extending groups

The synthesis and characterisation of a series of poly(S,S-lactides) and poly(RR/SS-lactides) end capped or chain extended with aldaric ester groups are described. The aldaric esters are prepared from acetyl protected d-gluconolactone, d-galactonolactone and d-mannonolactone by ring opening with butanol or 1,4-butanediol, under acidic conditions. The aldaric esters are fully characterised, including by NMR spectroscopy and mass spectrometry. They are used as co-initiators, with an ethylzinc complex, to enable the controlled ring opening polymerisation of S,S- and rac-lactide. Thus, a series of polylactides are produced with various carbohydrate chain end or extending groups and are fully characterised, including by NMR spectroscopy and gel permeation chromatography (GPC). The polymerisation kinetics are examined, under pseudo first order conditions, and indicate that chain transfer reactions are occurring more rapidly than propagation reactions. The degradation kinetics of the polylactides are examined under acidic conditions; the aldaric esters increase the degradation rates compared to unfunctionalised end groups.

2,2′-Dipyridyltrimethylsilylamine reacts with chloro- and bromomethyl(methyl)chlorosilanes to give Si-functional 1-(2-pyridone-(2′-pyridyl)imine) methylsilanes.Their solid state and solution structures have been determined.Depending on the halogen and the number of halogen atoms neutral pentacoordinate Si-species, RN-2-(C5H4NCH2SiMexCl3-x) (R = 2-C5H4N; x = 1 (2); x = 0 (3)) or ionic tetracoordinate Si-species +Br- (4) are obtained in solution and as solids.The solid compound with x = 2 (1) is also pentacoordinate at Si.In solutionthere is an interesting temperature-dependent equilibrium between the neutral pentacoordinate and the ionic tetracoordinate structure (at lower temperature, NMR) of 1.For the pentacoordinate species dissociation of the coordinative Si-N bond and formation of the neutral tetravalent silanes is suggested at higher temperature in solution.The temperature-dependent equilibrium between the isomers of 1 thus follows reversibly the SN2 pathway of nucleophilic substitution at silicon.The solid state structures of 1 and 3 and of 1-methyl-2-(2′-pyridyl)aminopyridinium chloride (5) are discussed.Structural differences between solid 1 and 3 are interpreted in terms of different stages of the SN2 reaction at silicon.

Two isomers of heteroleptic bis(bidentate) ruthenium(II) complexes with dimethyl sulfoxide (dmso) and chloride ligands, trans(Cl,Nbpy)- and trans(Cl,NHdpa)-[Ru(bpy)Cl(dmso-S)(Hdpa)]+ (bpy: 2,2?-bipyridine; Hdpa: di-2-pyridylamine), are synthesized. This is the first report on the selective synthesis of a pair of isomers of cis-[Ru(L)(L?)XY]n+ (L?L?: bidentate ligands; X?Y: monodentate ligands). The structures of the ruthenium(II) complexes are clarified by means of X-ray crystallography, and the signals in the 1H NMR spectra are assigned based on 1H?1H COSY spectra. The colors of the two isomers are clearly different in both the solid state and solution: the trans(Cl,Nbpy) isomer has a deep red color, whereas the trans(Cl,NHdpa) isomer is yellow. Although both complexes have intense absorption bands at lambda?440?450 nm, only the trans(Cl,Nbpy) isomer has a shoulder band at lambda?550 nm. DFT calculations indicate that the LUMOs of both isomers are the pi* orbitals in the bpy ligand, and that the LUMO level of the trans(Cl,Nbpy) isomer is lower than that of the trans(Cl,NHdpa) isomer due to the trans effect of the Cl ligand; thus resulting in the appearance of the shoulder band. The HOMO levels are almost the same in both isomers. The energy levels are experimentally supported by cyclic voltammograms, in which these isomers have different reduction potentials and similar oxidation potentials.
