Tempo → 4,8-Dioxa-3H-perfluorononanoic acid

Participants

Reaction Steps

50 mL of acetic acid, 0.137 g of manganese nitrate tetrahydrate, 0.159 g of cobalt nitrate hexahydrate, TEMPO (0.42 g), CH3CO2Na (2.24 g) and 10 g of 2,2,3-trifluoro-3-(1,1,2,2,3,3-hexafluoro-3-trifluoromethoxy-propoxy)-propan-1-ol were placed in a reaction vessel as described in example 17 except that a 100 mL vessel instead of a 200 mL vessel was used. The reaction was carried out and worked up as described in example 9. Distillation gave 7.29 g of acid (1.6 mmHg, 58° C.). Yield: 70%.
