The enantioselective synthesis of (2S)-2-phenylpropanol and (2S)-2-(4-iso-butylphenyl)propanol ((S)-Ibuprofenol) has been achieved by means of Horse Liver Alcohol Dehydrogenase (HLADH) in buffered aqueous solution or buffered organic solvent mixtures; under the reaction conditions, a dynamic kinetic resolution (DKR) process was realized with good reaction yields and enantiomeric ratios.

The oxidation of 3,5-di-tert.-butylphenyl N-methylcarbamate (Butacarb) has been studied in the flies Musca domestica and Lucilia sericata, grass grubs Costelytra zealandica and the mouse. In all species eleven oxidation products, which were formed by hydroxylation of the tert.-butyl groups and the N-methyl group, were detected.

The electrochemistry and electrogenerated chemiluminescence (ECL) of three phenanthrene derivatives, 3,6-diphenyl-9,10-bis-(4-tert-butylphenyl)phenanthrene (TphP, T1), 3,6-di(naphthalen-2-yl)-9,10-bis(4-tert-butylphenyl)phenanthrene (TnaP, T2), and 3,6-di(pyrene-1-yl)-9,10-bis(4-tert-butylphenyl)phenanthrene (TpyP, T3), are investigated in an acetonitrile:benzene (v:v = 1:1) solvent. Cyclic vol...

The reaction of the cyclotetraphosphane [ClP(μ-PMes*)]2 (, Mes* = 2,4,6-tri-tert-butylphenyl) with Ag[Al(OR(F))4] (R(F) = CH(CF3)2) resulted in a labile, dinuclear silver complex of , which eliminates AgCl above -30 °C. Its properties were investigated by spectroscopic methods, single crystal X-ray diffraction and DFT calculations.

The water-soluble gold(III) complex [Au(III)(butyl-C^N)biguanide]Cl (butyl-HC^N = 2-(4-n-butylphenyl)pyridine, BCN) displays cytotoxicity through S-phase cell cycle arrest and endoplasmic reticulum (ER) damage in HeLa cells, and shows a promising anti-angiogenic effect at sub-cytotoxic concentrations.

The molecule of the title compound, [Fe(C26H31)2], is located on an inversion center. The two cyclopentadienyl rings exhibit a staggered conformation, which results from the bulky bis(4-tert-butylphenyl)methyl substituents situated on opposite sides of the molecule.

A panchromatic dye was synthesized with an isoindigo core as a linker to bridge with a bis(4-tert-butylphenyl)phenylamine donor and a cyanoacetic acid acceptor for dye-sensitized solar cells, showing a broad spectral response and a high conversion efficiency of 7.55% under AM 1.5 conditions.
