| | Pentafluorobenzaldehyde Usage And Synthesis |
| Chemical Properties | Freshly distilled pentafluorobenzaldehyde is a colourless liquid with a strong odour; clear yellowish liquid after melting; a lachrymator; soluble in common organic solvents and practically insoluble in water. | | Uses | 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 micro extraction and gas chromatography-tandem mass spectrometry. It was used in the synthesis of novel, high molecular weight fluorinated aromatic polymers. | | Preparation | Pentafluorobenzaldehyde is prepared by the reaction ofpentafluorophenylmagnesium bromide, iodide or chloride, or of pentafluorophenyllithium with ethyl-ortho-formiate or 3,4-dihydro-6-methyl-3-(para-tolyl)-quinazoline methiodide. Higher yields of pentafluorobenza1dehyde have been obtained by the reaction with N-methy1formanilide. Pentafluorobenzaldehyde may be prepared also by the reaction of pentafluorobenzonitrile with anhydrous SnClz in ethereal solution of HCl with subsequent hydrolsis of the intermediate (62% yield). | | General Description | 2,3,4,5,6-Pentafluorobenzaldehyde reacts with 5-(aryl)dipyrromethanes to form a variety of meso-aryl [26]hexaphyrins. | | Precautions | Pentafluorobenzaldehyde is oxidized when exposed to light and air. It should be kept in a tightly stopped dark container. Pentafluorobenzaldehyde is about ten times as toxic as benzaldehyde, therefore it should be handled with caution. |
