In the title complex, [Pd(CH(3)COO)(2)(C(10)H(9)N(3))], the Pd(II) ion is four-coordinated in a slightly distorted square-planar environment by two pyridine N atoms of the chelating di-2-pyridyl-amine (dpa) ligand and two O atoms from two anionic acetate ligands. The dpa ligand coordinates the Pd(II) atom in a boat conformation of the resulting chelate ring; the dihedral angle between the pyrid...
Compared with the rapid deactivation of Pd/AC catalyst, an eco-friendly Pd-[DBU][Cl]/AC ([DBU][Cl], 1,8-diazabicyclo[5.4.0]undec-7-ene hydrochloride) catalyst enhanced stability was synthesized and applied in hydrochlorination acetylene. The Pd-20[DBU][Cl]/AC exhibits 96.7% acetylene conversion 98.9% selectivity vinyl chloride within 24 h evaluation under conditions T = 180 °C, GHSV(C2H2) 360 h...
There are two independent Pd(II) complex mol-ecules in the asymmetric unit of the title compound, [PdCl(2){Fe(C(5)H(5))(C(24)H(19)NP)}]·0.5CH(2)Cl(2). One ferrocenyl ring of one complex mol-ecule is disordered over two sites with half-occupancy for each component. Both Pd(II) cations adopt a distorted square-planar coordination geometry with a bidentate [2-(diphenyl-phosphino)phenyl-imino-meth-...
Mixed ligand complexes of the formula [M (phen) bdt] where M= Pd (II) or Pt(II), phen =1,10phenanthroline and bdt =1,2-benzenedithiolate have been synthesized and studied as photosensitizers of singlet molecular oxygen (1O2) production. It was observed that, Pt (II) complex shows a better photosensitizing ability as compared to its Pd (II) analogue. However, both Pd (II) and Pt (II) complexes a...
Pd(MME)Cl2 complex (MME = methionine methyl ester) was synthesised and characterized by physicochemical measurements. The reaction of [Pd(MME)(H2O)2](2+) with amino acids, peptides, or dicarboxylic acids was investigated at 25°C and 0.1 M ionic strength. Amino acids and dicarboxylic acids form 1 : 1 complexes. Peptides form both 1 : 1 complexes and the corresponding deprotonated amide species. ...
Respiratory chain enzyme activities were studied in lymphocytes from patients with Parkinson disease (PD) (n = 16) and age-matched control subjects (n = 15). The patients had received no therapy before the study was conducted. Complex I, III, and IV activities were significantly lower (P < 0.05) in patients than in control subjects. A complex I defect was found in one patient, whereas complex I...
We report here the development of Pd-supported catalysts for selective C-3 arylation free-indole using thiol-functionalized silica supports to anchor palladium centers. The (II) complex, Pd(OAc)2, was efficiently loaded into various mesostructured silicas at room temperature. These materials exhibit different contents surface SH groups (0.3 1.8 SH/nm2) and SH/Pd molar ratios from 6 65. It found...
Background and Aim: Parkinson Disease (PD) is a common cause of disability in the aged. PD patients need life long drug therapy and rehabilitation. This study was to evaluate the initial manifestations of PD. Materials and Methods: In this case-series study, 100 consecutive elderly patients with PD enrolled in a prospective case series study in Valie-e-Asr neurology clinic affiliated to Birjan...
The prevalence of Personality Disorders (PD) in a prison and its effect on prison social climate are studied. Our research shows a statistically significant relationship between diagnosis of PD and indicators of social climate disruption such as aggressive interpersonal conduct or compulsive demand for psychoactive drugs in medical consultations. PD is one of the most common mental disorders in...
Parkinson's disease (PD) is a neurodegenerative disorder that affects large numbers of people, particularly those of a more advanced age. Mitochondrial dysfunction plays a central role in PD, especially in the electron transport chain. This mitochondrial role allows the use of inhibitors of complex I and IV in PD models, and enhancers of complex IV activity, such as NIR light, to be used as pos...
