摘要：

The effect of beta-cyclodextrin on o-ethoxybenzenediazonium salt coupling with pyrrole, imidazole and 2-methylimidazole has been studied. The differences in the reaction course, the overall yield and products distribution have been analyzed. Experiments without cyclodextrins and selected reactions with alpha- and gamma-cyclodextrins have been performed for comparison. The results are discussed in terms of co-conformation of azole molecules embedded in cyclodextrin cavity.
