Yield:156-54-7 >= 95 %Spectr.

Reaction Conditions:

with water;sodium hydroxide; pH=12 for 0.00277778 h;

Steps:

1.e Example 1e DNP Hyperpolarization of Butyric Anhydride and Dissolution in the Presence of Strong Base for Hydrolysis
The composition from example 1b (25 mg, 0.16 mmol) was transferred from the Eppendorf tube to a sample cup and the sample cup was inserted into a DNP polariser. The composition was hyperpolarised under DNP conditions at 1.2 K in a 3.35 T magnetic field under irradiation with microwave (93.915 GHz). The sample was hyperpolarized for 75 min. (0243) The sample was dissolved in 4 ml water with added NaOH (50 μl of 12M solution). The pH of the dissolved sample was 12. The solution was collected directly into a 10 mm NMR tube and transferred to a 14.1 T magnet where a time series of 5 degree 1D 13C-NMR spectra were recorded with a total delay between the pulses of 1 s. The anhydride was quantitatively hydrolyzed (up to at least 95%) after 10 s. The butyric anhydride polarized well and was easily hydrolyzed to butyrate during the time of the experiment.
