The effect of micro-morphology of Bi2O3 on catalytic properties of Co/Bi catalyst for wet air oxidation of acetic acid

The novel phase transfer catalysts S-8 [4-(dimethyloctylammonium) propansultan] and DB-X [1,4-bis(triethylmethylammonium)benzene dibromide] were synthesized and employed for high conversion synthesis of dichlorocyclopropane from various olefins.This revised version was published online in December 2005 with corrections to the Cover Date.     

Sigmatropic Rearrangements in Phosphorylated 2-Azaallylic Systems

Abstract

Allylic and heteroallylic compounds are classical objects of organic chemistry and can serve as models in the investigation of various theoretical problems. The anions and 1,3-dipoles generated from azaallylic derivatives are widely used in the synthesis of cyclic and acyclic nitrogen-containing compounds.     

Dehydrohalogenation of adducts of dichlorocarbene with cyclooctene and its peripherally cyclopropanated analogs

Dehydrohalogenation of three isomeric adducts of dichlorocarbene with bicyclo[6.1.0]non-1-,-2-, and-4-enes under the action of potassiumtert-butoxide in DMSO was studied. In the course of dehydrohalogenation of the substrates under study, different isomerization processes, which were accompanied by repeated migrations of multiple bonds that formed, occurred depending on the structure of dichlorides, while no skeletal rearrangements were observed.
