    • Although used in large concentrations, bicarbonate is a catalyst so the oxidations described here are low E factor reactions, in contrast to stoichiometric activators where a leaving group becomes a byproduct. See Sheldon, R. A. J. Chem. Technol. Biotechnol. 1997, 68, 381.

    • Conversion rates are lower in mixed organic/aqueous solvents, in part because bicarbonate solubility decreases and less catalyst can be used; however, bicarbonate salts with alkylated ammonium cations can be used to increase catalyst solubility (Yao, H.; Richardson, D. E., work in progress).

    • 2 (30%, 360 mmol) were dissolved in 130 mL water, mixed with 240 mL of acetonitrile, and 4 mL of styrene (35 mmol) was added. The rt reaction was allowed to proceed in the dark without stirring for 24 h. The reaction mixture was diluted with 200 mL of water and extracted with chloroform (5 × 200 mL). The filtrate was washed with water (2 × 40 mL), dried, and concentrated by removal of solvent. Fractional distillation of the crude product gave 3.1 g of styrene oxide (75%).

    • 9 The best solvents for the DCC-activated epoxidation are hydroxylic ones such as methanol, ethanol or 2-propanol (except pure water).
