developed through the coupling of β-nitrostyrenes with sodium sulfinates under microwave irradiation. This methodology provides a convenient and efficient approach to various (E)-vinyl sulfones from readily available starting materials with excellent regioselectivity. The present oxidative reaction involves an efficient denitrative radical cross-coupling of β-nitrostyrenes with sodium sulfinates via using
Abstract Some new trans-aryl cyclopropylsulfones (II) have been prepared by the cycloaddition of dimethylsulfoxonium methylide to trans-styryl arylsulfones (I) by two different methods. It is observed that the reaction in presence of a phase transfer catalyst proceeds in a facile manner.

heterogeneous Cu catalysts and systematically evaluated their composition and catalytic activity in azide-alkyne cycloadditions as a model reaction. The use of sustainable graphite nanoplatelets (GNPs) afforded a stable CuI catalyst with good recyclability properties, which are compatible with flow conditions, and able to catalyze other reactions such as the regio- and stereoselective sulfonylation of alkynes (addition

Radical-mediated thiodesulfonylation of the vinyl and (alpha-fluoro)vinyl sulfones, derived from aldehydes and ketones, with aryl thiols in organic or aqueous medium provided access to vinyl and (a-fluoro)vinyl sulfides. The vinyl sulfides were formed predominantly with E stereochemistry independent of the stereochemistry of the starting vinyl sulfones. (C) 2009 Elsevier Ltd. All rights reserved.
