title: No-D NMR spectroscopy as a convenient method for titering organolithium (RLi), RMgX, and LDA solutions.
abstract: [reaction: see text] The concentration of organolithium, organomagnesium halide, and lithium diisopropylamide solutions can be reliably determined using No-D NMR spectroscopy by integration against the added internal standard 1,5-cyclooctadiene (COD) (or cyclooctene). In addition, common impurities and degradation products can be assessed.
