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; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...
A common method is halide metathesis. An example is the conversion of alkyl chloride into alkyl fluoride: . C 3 H 5-Cl + NaF → R-F + NaCl. This kind of reaction is called Finkelstein reaction. [2]
Metathesis reactions employing alkali metal fluorides are the simplest. [16] For aliphatic compounds this is sometimes called the Finkelstein reaction, while for aromatic compounds it is known as the Halex process. R 3 CCl + MF → R 3 CF + MCl (M = Na, K, Cs)
Reactions with ammonia give primary amines. Chloro- and bromoalkanes are readily substituted by iodide in the Finkelstein reaction. The iodoalkanes produced easily undergo further reaction. Sodium iodide is used as a catalyst. Haloalkanes react with ionic nucleophiles (e.g. cyanide, thiocyanate, azide); the halogen is replaced by the respective ...
Hans Finkelstein (17 May 1885, Leipzig, Germany - December 1938) was a German chemist. He is particularly known for the Finkelstein reaction developed by and named after him. [ 1 ] [ 2 ]
Triplet and higher multiple births nosedive. In 2004, of the people younger than 35 who gave birth with the help of IVF, 32.7% delivered twins, and 4.9% delivered triplets, according to doctors at ...
According to City of Delray Beach officials, Palm Beach County Fire Rescue provided assistance, taking a total of 12 people to the hospital with minor injuries.. Three firefighters were also ...
This reaction was developed by Alexander Williamson in 1850. [2] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction. This reaction is important in the history of organic chemistry because it helped prove the structure of ethers. The general reaction mechanism is as follows: [3]
