Abstract

¹H nmr spectroscopy has been used to demonstrate hydrogen–deuterium exchange in solutions of NaBH₄/NaB²H₄ in diglyme and KBH₄/KB²H₄ in 18-crown-6 ether/chloroform. Earlier observations of such exchange with LiBH₄/LiB²H₄ in an ethereal solvent were confirmed. Spectra were simplified by broadband decoupling of deuterium, facilitating quantitative measurement of the degree of exchange.
