Molecular modelling of an iodine(III) phenoxide was used as a starting point in the design of chiral aryl iodide catalysts for stereoselective oxidative dearomatization reactions. Using this approach, catalysts derived from 8-iodotetralone and tartaric acid were constructed and used to synthesize enantioenriched para-quinols from phenols.

INTRODUCTION AND OBJECTIVE In intensive pig production aerial contaminates are potential hazards for the health of animals and humans. In this study, the effect of fogging a low concentrated tartaric acid solution on pigs' health, environmental and hygiene parameters were evaluated in an inhabited fattening unit. MATERIALS AND METHOD Pigs were housed in separate units (control group n=109 and...

The kinetics of growth for chiral J-aggregates of H(4)TPPS(4) porphyrin have been investigated under different experimental conditions in the presence of tartaric acid. The observed rate constants and the anisotropy factor g show a defined dependence on the enantiomer used as a chiral templating agent.
