Intermolecular imine formation: condensation of organic molecules with hexammine Ru III and Pt IV ions

Abstract

A .C. T. 2600, Australia) Summary M(NH,),"+ (M = Rum and PtW) ions condense with dicarbonyl compounds to give chelates where the co-ordinated nucleophile is the effective agent in the reaction and the resulting, normally unstable, organic group is stabilised.

Hydrogen evolving systems. 2. The reduction of molecular nitrogen, organic substrates, and protons by vanadium(II)

“…At high concentrations of C2H2, C2H4 is formed almost exclusively and the reaction goes to completion within 2-3 min (Figure 1). In typical experiments, Mg(OH)2 (2000 µ ), containing 35 µ of V(OH)2, was reacted with C2H2 at 1 atm of pressure. After 10 min of reaction at 23 °C, the total yield of C2H4 was 32 µ , indicating that V(OH)2 acts as a two-electron reductant under these conditions.…”

Crystal structure and molecular geometry of [(.eta.5-C5H5)2Fe]2As4Cl10O2, the ferrocenium salt of a complex oxychloroarsenate(III) counterion

“…920 (2) A, As(2)-Cl(3) = 2.889 (2) A, and As(2')-C1(3) =3.062 (2) A. (The As(V)-Cl(3) distance of 3.349 (2) A…”

Reaction of nitrosylpentaammineruthenium(II) with ethylamine, methylamine, and hexaammineruthenium(III) ion to produce dinitrogen complexes

“…Dowex 50W-X4 resin was pretreated by the method of Taube and Deutsch12 to remove UV-absorbing impurities. Infrared spectra were obtained on a Perkin-Elmer 257 spectrophotometer and UV-visible spectra on Cary Model 14 and (~0.3 mmol) were added to 100 mL of aqueous methylamine (~2 M), ethylamine (~1 .1 M), or methylamine hydrochloride (~1.75 M) and allowed to stand until no further color change occurred (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) h). Addition of excess KBr, KI, or NaBF4 (~1 0 g) produced pale yellow precipitates which were collected by filtration, washed successively with 95% ethanol and ether, and air-dried.…”
