The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not. The reaction is driven toward products by mass action due to the precipitation of the poorly soluble NaCl or NaBr. An example involves the conversion of the ethyl ester of 5-bromovaleric acid to the iodide: WitrynaEnter the email address you signed up with and we'll email you a reset link.
Witrynalation detector was a NaI(Tl) crystal optically coupled to a phototube. The NaI(Tl) detector had an energy resolution of 8% at 662 keV, and the distance between the source and de-tector was maintained at 12 cm. The online analysis of the γ-ray spectrum was conducted using Spectrolate Lab version 3.4 computer software, as shown in Figure 3.
