Abstract:Previously unknown 1-vinylpyrrole semicarbazones, thiosemicarbazones, and guanylhydrazones have been obtained in 68.0–90.5% yield by the reaction of 1-vinylpyrrole-2-carbaldehydes with semicarbazide, thiosemicarbazide, and aminoguanidine. Dedicated to Academician B. A. Trofimov on his 70th jubilee. Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1384–1390, September, 2008.
Keywords:1-vinylpyrrole-2-carbaldehydes  guanylhydrazones  semicarbazones  thiosemicarbazones
