The 1H NMR spectrum of the carbonyl hydrogen, isolated by a dipolar-difference technique, is shifted downfield from that of neat formic acid, indicating that the hydrogen has become more acidic.doi:10.1016/0021-9517(81)90260-8Duncan, T. M...
The parent compound of carboxylic anhydrides-formic anhydride-has now been synthesized in ethereal solution at -78掳 C by four different methods, and charactrized by 1H-NMR, 13C-NMR, and IR spectroscopy. The anhydride undergoes partial decomposition to formic acid on distillation of the solutions...
A new method of preparing memantine hydrochloride, comprising the following steps: reacting 1-bromo-3,5-dimethyl adamantane and urea/formic acid, with formic acid also acting as the solvent; hydrolyzing with aqueous inorganic acid; alkalifying, extractin
