Finkelstein’s reagent

One of these consists in the substitution of iodine for the ester group attached to the primary carbon atom as the result of prolonged heating with sodium iodide in acetone solution (Finkelstein s reagent (20]). The reaction appears likely to consist in breaking the C—O linkage ... 

Finkelstein s reagent was first brought into use for this purpose by Oldham [17]. The secondary ester radical does not undergo this chemical reaction, but it may suffer hydrolysis followed by the formation of an OH group ... 

Sodium iodide in acetone solution (Finkelstein s reagent ) is most commonly used. By means of this reagent, a nitrate or a sulfonate ester group on a primary carbon atom is replaced by iodine. ...
