摘要：

5(6)-Fluoro-6(5)-substituted benzofuroxans were obtained by the reactions of 5,6-difluorobenzofuroxan with a number of nucleophiles, such as alkylamines, cycloalkylimines, sodium azide and sodium alkoxides. The features of tautomerism in the series of asymmetrical 5(6)-fluorobenzofuroxans in acetone solutions have been studied by H-1, C-13 and F-19 NMR. (C) 2003 Elsevier B.V. All rights reserved.
