Synthesis, crystal structure, antibacterial, cytotoxic, and anticancer activities of new Pd(II) complexes of tri-p-tolyl phosphine with thiones

Four Pd(II) complexes of general formula [Pd(L1)2(L2)2], where L1 = pyridine-2(1H)-thione, pyrimidine-2(1H)-thione, pyridine-4(1H)-thione, and pyridine-4(1H)-thione, L2 = tri-p-tolylphosphine, have been synthesized by direct reaction of K2[PdCl4] with phosphine and heterocyclic thiones ligands in 1 : 2 : 2 molar ratio. The complexes have been characterized by elemental analyses, FT-IR and multinuclear NMR spectroscopy. The complexes 1 and 2 were also characterized by single crystal X-ray diffraction which revealed that the Pd(II) atom adopted a nearly square planar geometry with two tri-p-tolyphosphine molecules bound in a trans fashion and also two pyridine-2(1H)-thione (1) or pyrimidine-2(1H)-thione (2) molecules trans to each other. The compounds were tested for antibacterial activity, DNA interaction by brine shrimp lethality bioassay, antitumor activity, and gel electrophoresis. The complexes demonstrated moderate activity against gram positive and gram negative bacterial strains in comparison with a standard drug imipenum. Their antitumor activity against MCF7 tumor cell line was determined to be comparable to that of doxorubicin. The investigated compounds demonstrated no cytotoxic effect in brine shrimp bioassay study.

Synthesis and characterization of new nitrate-bridged polymeric complexes of mercury(II) with phosphorus ylides

Reaction of phosphorus ylides of the type X-C6H4-COCH{double bond, long}PAr3 (X = Cl and NO2; Ar = phenyl and p-tolyl) with Hg(NO3)2 ¡¤ H2O in equimolar ratios using methanol as solvent are reported. X-ray crystal structure analysis of [Hg(ClC6H4C(O)CHPPh3)(NO3) (mu-NO3)]n ¡¤ (DMSO)n shows that the 1:1 complex adopts the noncentrosymmetric polymeric structure in the solid state with NO-3 anion bridges. Variation of temperature or concentration in a 31P NMR study indicates that the disappearance of satellites, due to coupling to 199Hg, occurs at increasing temperature or decreasing concentration.

Gold(III) derivatives with C(4)-aurated 1-phenylpyrazole

The reaction of 1-phenylpyrazole (HL), with gold(III) chloride has been studied. Besides a 1:1 adduct [Au(HL)Cl3] 1, where the ligand is bonded through the nitrogen atom, several C(4) aurated species have been isolated. Thus treatment of [AuCl3]2 with HL in dichloromethane solution affords a complex, [Au(L)Cl2.HCl]n, 2, where the gold atom is bonded to the 4-carbon atom of the pyrazole ligand. Deprotonation of complex 2 by means of the not coordinating base 1,8-bis(dimethylamino)naphthalene (proton sponge), B, affords the salt [BH][Au(L)Cl3], 3, whereas reaction of 2 with 3,5-Me2py and PPh3 (molar ratio 1:2) gives the neutral species trans-[Au(L)(3,5-Me2py)Cl2], 4, and cis-[Au(L)(PPh3)Cl2], 5, respectively. The structure of compound 4 solved by X-ray diffraction, unambiguously shows the anionic ligand L bonded to the gold ion through the C4 atom. Alternatively, compounds 4 and 5 can be obtained in two steps, i.e. deprotonation of 2 with NaOH to give [Au(L)Cl2]n, 6, and reaction of 6 with 3,5-Me2py and PPh3, respectively. The new species were characterized by elemental analyses, conductivity measurements, IR, NMR and FAB-MS spectroscopy.

Rhenium(V) complexes with thiolato and dithiolato ligands: Synthesis, structures, and monomerization reactions

The new compound {(PhS)2ReO(mu-SPh)}2, 1, was synthesized from Re2O7 and PhSH and then used as the synthon for a number of hitherto unknown oxorhenium(V) compounds. Reactions between dithiols and 1 (2:1 ratio) afford {PhSReO(dt)}2, where the dithiols, dtH 2, are 1,2-ethanedithiol (edtH2), 1,3-propanedithiol (pdtH 2), 1,3-butanedithiol (pdtMeH2), 1,2-benzenedithiol (bdtH2), 2-(mercaptomethyl)thiophenol (mtpH2), and 2-mercaptoethyl sulfide (mesH2). Similar reactions carried out with a 3:1 ratio of dtH2 to 1 afford [(ReO)2(dt)3], dt = edt, pdt. When NEt3 was introduced prior to the 3:1 reaction between edtH2 and 1, a compound containing an anionic complex was isolated, [PPh4][ReO(edt) 2]. The new compounds were characterized analytically, spectroscopically, and crystallographically. The Re-O groups in two of the compounds, 1 and {ReO(mu-SPh)(bdt)}2, exist in rare anti orientations; the others adopt the more familiar syn geometry, as discussed. Selected monomerization reactions of {PhSReO(dt)}2 were also carried out: {PhSReO(dt)}2 + 2L = 2[PhSReO(dt)L]. The rate for L = 4-phenylpyridine is given by v = {Ka[L] + Kb[L] 2} ¡Á [{PhSReO(dt)}2], as it is for the reactions of {MeReO(dt)}2; for all of these compounds, the reaction proceeds nearly entirely by the third-order pathway. Values of kb/L 2 mol-2 s-1 at 25.0C are 5.8 ¡Á 102 (mtp), 2.97 ¡Á 103 (pdt), 4.62 ¡Á 105 (edt), and 3.87 ¡Á 105 (bdt). The rate law for the reactions of {PhSReO(dt)}2 with L = PAr3 is v = ka[L]/{1 + K[L]} ¡Á [{PhSReO(dt)}2]. For PPh3, values at 25.0C of Ka/L mol-1 s-1 (k/L mol -1) for {PhSReO(dt)}2 are 9.64 ¡Á 10-2 (1.87) for mtp, 3.43 ¡Á 10-2 (0.492) for pdt, 1.91 (1.42) for edt, 1.84 ¡Á 10-2 (0.82) for bdt, and 1.14 ¡Á 10 3 (10.6) for 1. Mechanisms are proposed that are consistent with the data obtained and with earlier work.

Structure of complexes and catalytic oxidation of triarylphosphine in the reaction of 9-phenyl-9-phosphafluorene with bis(acetylacetonato)palladium

Complex formation of 9-phenyl-9-phosphafluorene with bis(acetylacetonato)palladium in benzene and acetonitrile was studied by means of NMR, IR, and UV spectroscopy. The structure of the resulting complexes, as well as specific features of catalytic oxidation of the arylphosphine and the reduction of Pd(II) to Pd(0) to form the complex Pd(PC18H13)4 were explored. 9-Phenyl-9-phosphafluorene gives two types of complexes with Pd(acac)2). The first ones are similar to triphenylphosphine complexes, and the others (pi complexes) are formed by coordination of the planar aromatic pi system of the phosphine to the plane of Pd(acac)2.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1038-95-5 is helpful to your research., 1038-95-5
