Abstract: | The possibility of synthesizing functionally substituted furazans by alkylation of lithium derivatives of 3-methyl-4-R-furazans was investigated. It was shown that one or both methyl groups of 3,4-dimethylfurazan could be lithiated and alkylated. A series of previously unknown furazan derivatives was obtained.For previous communication, see [1].N. D. Zelinskii Institute of Organic Chemistry, Russian Academy of Sciences, 117913 Moscow.
