Alkylation of benzofuranones (I) with alcohols in the presence of a chiral biscinchona catalyst affords the 3-alkylated product with good enantioselectivities up to 83% e.e. [ABSTRACT FROM AUTHOR]

MnO2/Fe3O4/graphene oxide (GO) and MnO2/Fe3O4/graphene nanocomposites are prepared by a two-step reaction involving solvothermal reaction of an ultrasonicated dispersion of graphene oxide and Fe(acac)3 in ethylene glycol with and without the addition of N2H4 hydrate (autoclave, 180 °C, 16 h) followed by MnO2 coating in an KMnO4 aqueous solution (circulator, 80 °C, 3 h, pH 5 and pH 2).

Starting from 2-benzylidenebenzofuran-3-ones the synthesis of chiral dihydropyran-fused benzofurans is elaborated. [ABSTRACT FROM AUTHOR]

The title species (IV) are prepared through a facile one-pot reaction of substrates (I) and (II) with alcohols. The yield goes down with increased steric hinderance of the alcohol. Thus, isopropanol and tert-butanol give only traces of the target products. [ABSTRACT FROM AUTHOR]

Chiral 3,3′-disubstituted benzofuranones are synthesized from the title addition in excellent yields with very good diastereoselectivities and enantioselectivities. [ABSTRACT FROM AUTHOR]

Highly concentrated aqueous solutions of LiN(SO2CF3)2 (5-20 M at 25 °C) are used as an electrolyte in a CR2032-type coin cell containing either LiMn2O4 or LiNi0.8Co0.15Al0.05O2 as the cathode and Cu-leached Mo6S8 Chevrel phase as the anode separated by glass fiber fabrics. [ABSTRACT FROM AUTHOR]
