Abstract

Abstract A large variety of C-aryl and C-alkyl nitrones were synthesized within 0.5–15 min via the condensation of aldehydes with N-(methyl, phenyl, or t-butyl) hydroxylamines over MgO by hand-grinding with an agate mortar. These reactions were investigated under different conditions and over different solid supports including basic alumina, montemorillonite, MgO, and molecular sieves (pore size 3 Å). In the more interesting ...
