The Schiff base ligand, HSB5FISA (H1), obtained by the condensation of S-benzyldithiocarbazate with 5-fluoroisatin, has been employed to synthesize a new cadmium(II) complex, Cd(SB5FISA)2 (2) (SB5FISA = monoanionic form H1). complex characterized elemental analysis, molar conductivity, magnetic susceptibility, inductively coupled plasma atomic emission spectroscopy (ICP-AES), Fourier-transform ...

Two new coordination polymers, namely, poly[[μ3-3-(1H-benzimidazol-2-yl)propionato]zinc(II)], [Zn(C10H8N2O2)] n , (1), and poly[bis-[μ2-3-(1H-benzimid-azol-2-yl)propionato]cadmium(II)], [Cd(C10H8N2O2)2] n , (2) have been synthesized from 3-(1H-benzoimidazol-2-yl)propanoic acid ligands through a mixed-ligand synthetic strategy under a solvothermal environment, and studied by single-crystal X-ray...

Allylic alcohols can be isomerised into carbonyl compounds by transition metal complexes. In the last few years, catalyst design and development have resulted in highly efficient isomerisations under mild reaction conditions, including enantioselective versions. In addition, the isomerisation of allylic alcohols has been combined with C-C bond forming reactions when electrophiles such as aldehy...

Positron emission tomography (PET) is becoming more frequently used by medicinal chemists to facilitate the selection of the most promising lead compounds for further evaluation. For PET, this entails the preparation of 11C- or 18F-labeled drugs or radioligands. With the importance of chirality and fluorine substitution in drug development, chemists can be faced with the challenge of preparing ...

on time supply of materials in construction projects is very important. therefore, coordinating a project with key suppliers, while ensuring the timely supply of materials, make the minimum costs of project. one way to create this coordination is integrated inventory planning which has been accomplished in this study. it is necessary to mention that such a model is considered np_hard in terms o...

The variability in leaf form nature is immense. Leaf patterning occurs by differential growth, taking place during a limited window of morphogenetic activity at the marginal meristem. While many regulators have been implicated designation and patterning, how these effectors interact to generate particular still not well understood. We investigated interaction among different tomato (Solanum lyc...

In the previous paper (1) a procedure was outlined for the isolation of a highly purified, apparently crystalline, blue-green colored copper protein from horse liver. The precipitate obtained in step 8 of the isolation procedure (1), contains a number of proteins of potential biochemical interest. Two of these proteins, in addition to the copper protein, have been separated by fractionation wit...

Organometallic complexes have unique physico-chemical properties, which have been widely used in homogenous catalysis, for example, for the synthesis of lead compounds and drug candidates. Over the past two decades, a few scientists from all over the world have extended the use of the specific characteristics of these compounds (e.g. structural diversity, possibility of ligand exchange, redox a...
