Pyrophosphoric acid → Tris-(tributylammonium) pyrophosphate

Participants

Reaction Conditions

Reaction Steps

Tris-(tributylammonium) pyrophosphate was prepared by treating pyrophosphoric acid (293 mg) in water (2.0 mL) with tributylamine (1.2 mL). The mixture was stirred vigorously at 0° C. for 10 min, and then at room temperature (RT) for 1 h. The water was removed by lyophilization; the residue was further dried by coevaporation with pyridine (3×5 mL) and toluene (5 mL), and then by evacuation (0.25 mm pressure, 12 h). The tris-(tributylammonium) pyrophosphate residue was dissolved in dimethylformamide (2.5 mL) and the solution used for subsequent reactions.
