Description

General description

Photchlorination of butyryl chloride in liquid phase has been investigated.

Application

Butyryl chloride can be used as:

• A reagent in the acylation of thiophene in the liquid phase catalyzed by zeolites.
• A source of CO and -Cl in the chlorocarbonylation of aryl bromides to yield acid chlorides.
• An intermediate in the synthesis of aryl [¹¹C]methylsulfones for PET applications.
