| N-Ethyl-N-isopropylpropan-2-aminium 4-Oxo-3-(perfluoropyridin-4-yl)-1,5-dioxaspiro[5.5]undec-2-en-2-olate >=95% Usage And Synthesis |
| Uses | Access to diverse set of (hetero)aromatics via Weaver Meldrum’s Acid reagents, thermally and hydrolytically stable. | | Uses | This compound undergoes cycloreversion to form the fluoro(hetero)aryl ketene, which undergoes efficient coupling with nucleophiles and allows rapid incorporation of highly fluorinated α-fluoro(hetero)aryl acetic acid derivatives. | | General Description | N-Ethyl-N-isopropylpropan-2-aminium 4-oxo-3-(perfluoropyridin-4-yl)-1,5-dioxaspiro[5.5]undec-2-en-2-olate is a fluoroarylated-Meldrum′s acid adduct. It can be prepared by reacting pentafluoropyridine with cyclohexyl-Meldrum′s acid in the presence of N,N-diisopropylethylamine and acetonitrile. |
