Reaction Conditions

Reaction Steps

The perfluoro-6,11-dioxahexadecanediamide (16.6 g, 0.023 mole) was mixed with an excess of phosphorus pentoxide, placed in a distillation flask and heated to 210° C for 2 hours. The reaction mixture was cooled, a vacuum of 105 mm was applied and heat was reapplied. The fraction boiling between 120°-125° C at 105 mm was collected (15.3 g, 96% yield). Analysis of the product confirmed the dinitrile structure. Infrared and nuclear magnetic resonance 1H and 19F were consistent with the structure. Mass spectral analysis, calculated M+ 684, found M+ 684 and elemental analysis were consistent with the proposed dinitrile structure.
