New trifluoromethylated pyridines from functionalized N1-acylacetamidrazones: New trifluoromethylated pyridines from functionalized N1-acylacetamidrazones. Cocco, Maria Teresa; Congiu, Cenzo; Onnis, Valentina; Bernard, Angela Maria; Piras, Pier Paolo (Dip. 17129-06-5 and 187143-84-6 are also occured in this study. Farm. Chim. Tecnol., Universita, Calgliari I-09124, Italy). Journal of Heterocyclic Chemistry, 33(6), 1771-1773 (English) 1996 HeteroCorporation. CODEN: JHTCAD. ISSN: 0022-152X. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Ten polyfunctionalized trifluoromethylpyridines I (R = CO2Et, CN; R1 = Me, i-Pr, benzyl, p-chlorobenzyl, Ph) were readily synthesized in 52-91% yields from EtOCH:CHCOCF3, using RCH2C(NH2):NNHCOR1 as starting material. .

Condensation of methylhydrazine with 4-ethoxy-1,1,1-trifluoro-3-buten-2-one: Condensation of methylhydrazine with 4-ethoxy-1,1,1-trifluoro-3-buten-2-one. A reinvestigation. Pavlik, James W.; Ayudhya, Theppawut Israsena Na; Tantayanon, Supawan (Department of Chemistry and Biochemistry, Worcester Polytechnic Institute, Worcester, MA 01609, USA). Journal of Heterocyclic Chemistry, 39(5), 1025-1027 (English) 2002 HeteroCorporation. CODEN: JHTCAD. ISSN: 0022-152X. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) In contrast to previous reports, 4-ethoxy-1,1,1-trifluoro-3-buten-2-one was obsd. to react with methylhydrazine in refluxing ethanol to yield 1-methyl-3-(trifluoromethyl)pyrazole and 4,5-dihydro-1-methyl-5-(trifluoromethyl)pyrazol-5-ol. 17129-06-5 are also occured in this study. The later compd. undergoes acid catalyzed dehydration to 1-methyl-5-(trifluoromethyl)pyrazole. . 17129-06-5 is just another one chemical used in this study..
