“…The equilibrium constant for this reaction has been measured many times for the gaseous phase (see, for example, (13,14)) but data for solutions are scarce. Gold and Tomlinson (14) measured the equilibrium constant by using 1 H NMR spectra similar to those given in Ref.…”

“…A literature survey showed that the isotopic disproportionation constant for liquid HDS, Kl, represented by reaction [I], has not been experimentally determined, although a value for the comparable constant for the H20/D,0 system has been reported (3). KI These equilibria are of considerable interest in that they are not subject to deviation (4,5) from the Born-Oppenheimer (B .O.)…”

The deuteron–proton liquid phase isotopic disproportionation constant in hydrogen sulphide, K1, defined for the equilibrium[Formula: see text]has been measured at 25.7 °C. The value of K1 was 3.99 ± 0.11, based upon direct measurements of the concentrations of the three molecular species H2S, HDS, and D2S by 1H and 2H nuclear magnetic resonance spectroscopy (nmr) of carefully purified samples. This compares with the theoretical vapour phase isotopic distribution constant Kv = 3.92, calculated from ideal gas vapour phase isotopic partition function ratios (1, 2).

It has been shown that the formation of anils from anilines and aliphatic ketones is homogeneously catalyzed by a variety of metal complexes. The products of the reactions have been unambiguously identified by preparing the anils using other synthetic routes. The catalysis is quite general and the system is therefore suitable for a systematic catalytic study varying both the catalysts and the substrates. The related reactions of anil hydrolysis and transimination may also be studied. The catalysts used, thiourea complexes of Co(II), Ni(II), and Zn(II), vary in their effectiveness by more than two orders of magnitude. In the present paper experiments defining the catalytic system are described. The equilibrium constants for the complexation of all the substrate molecules have been determined. Qualitative rate data on various ligand exchange and proton transfer steps is presented to demonstrate that such reactions cannot be rate determining in the overall catalytic reactions.
