Question

what is swartz reaction?explain briefly

Answer 1

The replacement in organic compounds of, most often, chlorine by fluorine through the action of antimony trifluoride (Sbf3 ).The reaction is usually carried out in the presence of Sb salts in which antimony displays an oxidation state of +5.

The Swartzs reaction is used in laboratory work. A variant of the reaction—fluorination using anhydrous hydrogen fluoride (HF) in the presence of catalytic quantities of Sb salts in which antimony displays oxidation states of + 3 and + 5—has industrial importance and is used in the production of Freons. The reaction was discovered and refined by the Belgian chemist F. Swarts in the late 19th and early 20th centuries.

Swarts' reaction is generally used to get alkyl fluorides from alkyl chlorides or alkyl bromides.
