A new method for the preparation of (E)-β-alkylstyrene derivatives has been developed via the addition of a benzyl or alkyl radical to β-nitrostyrenes using di-tert-butyl peroxide (DTBP) as the oxidant in the presence of Cu powder catalyst. The C–H bonds in various toluene derivatives, ethers, alkanes and alcohols were successfully converted into C–C bonds to yield the corresponding (E)-β-alkylstyrene

The efficient base-catalyzed synthesis of 3-substituted2-aminonaphtho[2,3-b]furan-4,9-dione derivatives from readily available precursors such as 2-hydroxy-1,4-naphthoquinone and nitroalkenes under aqueous conditions is described. Interesting features of this methodology are the conversion of a nitro functionality into an amino functionality in the absence of a reducing agent and the development of

Beta functionalization of oxoporphyrinogens as H‐bonddonor catalysts with binding site designed for dual activation of substrates is reported. Introduction of the β‐substituents enables the catalysis of 1,4‐conjugate additions, sulfa‐Michael additions and Henry/aza‐Henry reactions at low catalyst loadings (≤ 1 mol‐%) under mild conditions.
Geometrically Selective Denitrative Trifluoromethylthiolation of β-Nitrostyrenes with AgSCF<sub>3</sub> for (<i>E</i>)-Vinyl Trifluoromethyl Thioethers

An efficient copper(II)-promoted denitrative trifluoromethylthiolation under mild reaction conditions has been developed for vinyl trifluoromethyl thioethers to construct Cvinyl–SCF3 bonds with stable AgSCF3 as a source of the trifluoromethylthio. This reaction system tolerates a broad range of functional groups to commendably achieve a high product yield and excellent stereoselectivity of E/Z.
