  作者：Chhanda Mukhopadhyay、Arup Datta

  DOI：10.1002/jhet.9

  日期：2009.1

  aldehydes were allowed to react in one-pot operation to give 2-aryl-benzothiazoles in excellent yields in the presence of Dowex 50W in water. Very high yields coupled with the ease of work-up procedure, formation of no side products, employment of “reusable” catalyst, and “green” synthesis in aqueous medium without maintaining anhydrous reaction conditions are the most important aspects of this methodology
