Abstract
1. The action of sodium amide in ammonia on 4-chloroethynyl-N-alkylpyrazoles having a methyl group at position 5 leads to the formation of rearranged substitution products, i.e., the respective 5-(aminomethyl)-pyrazolylacetylenes. A suggestion is made about the mechanism of the reaction. 2. Under the same conditions 4-bromo- or 4-iodoethynyl-5-methylpyrazoles, like phenylchloroacetylene, exchange the halogen atom for sodium. At the same time a small amount of the aryl- or heteroarylacetonitrile is formed.
