Beschreibung

Allgemeine Beschreibung

Treatment of 4-formylmorpholine with sulphur tetrafluoride in the presence of potassium fluoride gives 4-(trifluoromethyl)morpholine in excellent yields. 4-Formylmorpholine reacts with series of 2-alkyl-2-cyclohexen-1-ones in the presence of POCl₃ to give the corresponding 3-alkyl-2-chloro-5,6-dihydrobenzaldehydes and allylic alcohols (by-product).

Anwendung

4-Formylmorpholine has been used in the preparation of:

• adenine hydrochloride labelled with ¹⁴C
• terphenyl dialdehyde
