Deuterated ethyl benzene

Deuterated ethyl benzene Benzoyl chloride Trimethylorthoformate... 

To 300 ml deuterated ethyl benzene (degree of deuteration 99.4%), in which was suspended 7.6 g of 5% Pd on BaS04 catalyst, was added 54.7 g of freshly distilled benzoylchloride. Via a gas inlet tube, D2-gas was bubbled... 

Furthermore, Venuto (77, 78) has applied a special type of LFER, the Brown selectivity relationship (79), to the deuteration (series 50) and ethylation (series 51) of toluene and benzene catalyzed by zeolites. The Brown equation... 

Complete analyses of the various deutero-ethylenes and deutero-ethanes were first obtained by Turkevich et at. (4), using a nickel wire, and this type of information has since been reported by Wilson et al. 5) for a bulk nickel catalyst and by Kemball 6) for a series of evaporated metallic films. In all cases, the ethanes produced range over the complete spectrum from do-ethane to do-ethane, and Kemball showed that it is possible to correlate the nature and the amount of the deutero-ethylenes formed over metallic films with the distribution of deuterium in the ethanes. Although the detailed mechanisms of the exchange and deuteration of ethylene are still the subject of controversy, it is clear that both are closely related and both involve the half-hydrogenated state, i.e., the adsorbed ethyl radical, as an intermediate. The main objective of the present research was to extend such studies to the benzene-deuterium system. 

If a 60 MHz NMR sp>ectrometer is used to determine the proton NMR of benzocaine, the amino protons may partially overlap the quartet in the ethyl group. If this is the case, a small amount of deuterated benzene can be added to shift the broad peak for the -NH2 group away from the quartet Carpenter, S. B. R. H. Wallace. A Quick and Easy Simplification of Benzocaine s NMR Spectrum.. Chem. Educ. 2006,83 (Apr), 637. A higher-field NMR spectrometer, such as obtained on a 300 MHz instrument, also avoids the overlap problem.
