- 3,5-Diamino-1,2,4-triazolium tetrafluoroborate (LH)BF4 and hexafluorosilicate (LH)(2)SiF6 have been isolated and characterized by single-crystal X-ray structure determination. IR spectroscopy, mass spectrometry, solubili...
- Unusual beta,beta '-coupling and beta-alkylation of methyl 2,3,3-trifluoropropenoate by lithium diorganocuprates
[作者:HAJDUCH JAN; PALETA OLDRICH,期刊:Journal of Fluorine Chemistry, 页码:143-146 , 文章类型: Article,,卷期:2011年132-2]
- Methyl 2,3,3-trifluoroprop-2-enoate (1) reacts with lithium diorganocuprates in two ways, by fluorine substitution at C-3 with alkyl or aryl, or by beta,beta' CC-coupling. The reaction product was strongly dependent on t...
