Description

General description

2,3,4,5,6-Pentafluorobenzaldehyde reacts with 5-(aryl)dipyrromethanes to form a variety of meso-aryl [26]hexaphyrins.

Application

2,3,4,5,6-Pentafluorobenzaldehyde was used in the synthesis of novel, high molecular weight fluorinated aromatic polymers by superacid-catalyzed polyhydroxylation reaction of fluorinated carbonyl-containing compounds. 2,3,4,5,6-Pentafluorobenzaldehyde was used as derivatization reagent in a study to develop a sensitive method for the determination of primary amines in sewage sludge by headspace solid-phase microextraction and gas chromatography-tandem mass spectrometry.
