  Water-soluble N-oxyl compounds-mediated electrooxidation of alcohols in water: a prominent access to a totally closed system

  摘要：

  Electrooxidation of alcohols in water involving water-soluble N-oxyl compounds (WS-TEMPOs) proceeded smoothly to afford the corresponding ketones and aldehydes in good yields. Notably, most of WS-TEMPOs in water remained intact after the electrolysis. The aqueous solution containing WS-TEMPOs was recovered easily and repeatedly used for the electrooxidation of alcohols, offering a totally closed system. (c) 2005 Elsevier Ltd. All rights reserved.

  Oil-in-water nanoemulsion which consisted of TEMPO, amphiphilic alcohols, and water offered unique reaction environments for electrooxidation of the alcohols to give the corresponding carboxylic acids in good to excellent yields. (c) 2009 Elsevier Ltd. All rights reserved.
