Tuning the mesomorphic properties of liquid-crystalline dibenzotetraaza[14]annulenes - Discotic nematic phases of tetraalkoxy- substituted derivatives
Grolik, Jaros?aw,Dudek, ?ukasz,Eilmes, Julita
, p. 5127 - 5130 (2012/09/25)
A homologous series of five tetrasubstituted dibenzotetraaza[14]annulene- based discotic mesogens was prepared and studied using polarizing optical microscopy (POM) and differential scanning calorimetry (DSC). A nematic phase was identified for the product bearing two peripheral isobutoxy and two dodecyloxy substituents.
Synthesis of bulky 1,2-dialkoxy- and 1,2,3-trialkoxy-arenes
Stephan, Michel,Zupancic, Borut,Mohar, Barbara
experimental part, p. 6308 - 6315 (2011/09/19)
A large series of bulky 1,2-dialkoxy- and 1,2,3-trialkoxy-benzenes was efficiently prepared via Williamson etherification. Preparation of their contiguous bromine-containing derivatives was also achieved.
INSECTICIDAL CARBAMATES EXHIBITING SPECIES-SELECTIVE INHIBITION OF ACETYLCHOLINESTERASE (AChE)

Page/Page column 11, (2009/04/24)
The present invention includes insecticidal carbamates that are useful, for example, for the control of insects, such as mosquitoes, which can be used in applications where exposure to and/or contact with humans is likely. The insecticides of the present invention include phenyl N-methyl carbamates and compositions comprising them that exhibit species-selective inhibition of acetylcholinesterase (AChE) and are preferably toxic to mosquitoes but not humans. Of particular interest are compounds of Formula (I) and Formula (II): Compounds of Formula (I) and Formula (II) are especially suitable for insecticide treated nets and indoor residual spraying for mosquito control.
The Baeyer-Villiger Oxidation of Aromatic Aldehydes and Ketones with Hydrogen Peroxide Catalyzed by Selenium Compounds
Syper, Ludwik
, p. 167 - 172 (2007/10/02)
A series of organoselenium compounds was investigated as activators of hydrogen peroxide in the Baeyer-Villiger oxidation.As a result, a convenient and cheap method for transformation of aromatic aldehydes, having polycondensed ring systems or electron-donating substituents, and polymethoxy derivatives of acetophenone, into phenols was elaborated.This method utilizes hydrogen peroxide activated by areneseleninic acids, as oxidizing agent.
