• Esterification of Aldehydes and Alcohols with Pyridinium Hydrobromide Perbromide in Water
  作者：Shinsei Sayama、Tetsuo Onami

  DOI：10.1055/s-2004-835630

  日期：——

  The direct esterification of aldehydes and alcohols was carried out with pyridinium hydrobromide perbromide in water at room temperature. A variety of aldehydes were converted to respective ester derivatives with alcoholssuch as methanol, 1,2-ethanediol, 1,3-propanediol. Further, a variety of aliphatic alcohols were also converted to the corresponding Tishchenko-like dimeric esters in good yields under
