Background and objectives: Herbal aromatic waters are one of the products used in the Iranian traditional medicine. These products have small amount of essential oil. The purpose of this study was to identify the effective substances of herbal aromatic waters by various techniques (GC/FID and GC/MS). It is hoped that with assessment of these compounds by mentioned techniques a ...

Neophylpalladium complexes of the type [Pd(CH(2)CMe(2)Ph)(N-O)(L)], where N-O is picolinate or a related bidentate, monoanionic ligand (6-methylpyridine-2-carboxylate, quinoline-2-carboxylate, 2-pyridylacetate or pyridine-2-sulfonate) and L is pyridine or a pyridine derivative, efficiently catalyze the oxidation of a range of aliphatic, benzylic and allylic alcohols with oxygen, without requiri...

Dynamic kinetic resolution (DKR) is one of the most attractive methods for enantioselective synthesis. In reported studies, lipase B from Candida antarctica (CALB) immobilized on siliceous mesoporous cellular foams (MCF) functionalized with different hydrophobic groups, and two ruthenium complexes substituted cyclopentadienyl ligands were investigated as catalysts chemoenzymatic DKR (rac)-1-phe...

Palladium nanoparticles, with core sizes of ca. 2.5 nm, were easily synthesized by chemical reduction Na2PdCl4 in the presence hydroxyethylammonium salts and proved to be efficient for selective hydrogenolysis various aromatic, alkylphenyl, aliphatic epoxides water as green solvent. Capping agents metal species screened define most suitable micellar nanoreactors on two target substrates industr...

Adults, particularly males, of a papilionid butterfly, Papilio machaon hippocrates, emit a fairly strong scent perceivable by humans. We have identified a variety of volatile compounds (hydrocarbons, alcohols, aldehydes, ketones, esters, and so on) from the wings and bodies of both sexes of the butterfly. Male wings secreted n-dodecane, linalool and geranylacetone as major components together w...

Halohydrin dehalogenase (HheC) from Agrobacterium radiobacter AD1 catalyzes the dehalogenation of vicinal haloalcohols by an intramolecular substitution reaction, resulting in the formation of the corresponding epoxide, a halide ion, and a proton. Halide release is rate-limiting during the catalytic cycle of the conversion of (R)-p-nitro-2-bromo-1-phenylethanol by the enzyme. The recent elucida...
