설명
2-chloro-6-(trifluoromethyl)pyridine, 2-chloro-5-(trifluoromethyl)pyridine and 3-chloro-4-(trifluoromethyl)pyridine were each converted into the three possible carboxylic acids 2, 4, 6,8, 10, 12, 16, 17 and 20. This was achieved by employing several, but not all of the organometallic “toolbox methods”: transformation of a more basic organometallic species into a less basic isomer by transmetalation-equilibration.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
