Exchange in liquid ammonia

Nesmeyanov and co-workers, Izv. Akad. Nauk SSSR, Otd. Khim. Naukt 1949, 592, 598. [Pg.98]

ND3 and KND2 lead also to isotope exchange in olefins, though here appreciably more slowly. A small amount of replacement of hydrogen by deuterium has even been observed for some aliphatic hydrocarbons. [Pg.99]

The present paper is a brief review of investigations concerned with the study of hydrogen exchange in liquid ammonia, which have been carried out by the author in collaboration with Yu. P. Vyrskii, N. M. Dykhno, E. A. Izrailevich, E. A. Yakovleva, E. N. Zvyagintseva, A. V. Vedeneev, Yu. I. Ranneva, and other workers at the Isotope Reaction Laboratory. [Pg.157]

Experiments on hydrogen exchange in liquid ammonia have been carried out in the temperature range between —40° and 120° with... [Pg.158]

Comparison of results on hydrogen exchange in liquid ammonia and in other solvents can be used to obtain information on the nature and mechanism of hydrogen isotope exchange reactions. [Pg.196]

Amide exchange in liquid ammonia In dry liquid ammonia, the rate of reaction (1)... [Pg.310]

The rate at which protons are exchanged in liquid ammonia has been measured by n.m.r. techniques . Three peaks appear in the proton magnetic resonance spectrum of pure liquid ammonia due to spin-spin coupling of the protons with the i N-nucleus. When a trace of ammonium salt is added the signal changes to a single line, which is attributed to... [Pg.41]
