General description

Tetrahydrofuran-d8 (THF-d8, TDF) is a deuterated NMR solvent useful in NMR-based research and analyses. 1H NMR line shape analysis of the exchange rates of proton between methanol and acetic acid dissolved in THF-d8 was reported. It participates as a solvent in the synthesis of deuteriotris[bis(trimethylsilyl)amido]thorium and deuteriotris[bis(trimethylsiiyl)amido]uranium. Dynamic NMR spectroscopic study of 15N,15N′-dipentadeuterophenylformamidine (DPFA) has been studied in THF-d8.
