Method for production of aziridines and N-vinylamides

In the production of aziridines or N-vinyl amides respectively from an alkanolamine or an alkanolamide by the known method comprising a reaction step, a collecting step and/or a condensation step, a purifying step, and a recovering step, this invention is directed toward preventing formation of a solid substance in the vacuum pumps and the vacuum lines. The object of this invention is accomplished by performing the decompression at the purifying step and the decompression at the recovering step in mutually different decompression systems.

SYNTHESIS OF METHYLPYRIDINES IN THE PRESENCE OF Pd COMPLEXES CONTAINING S

Synthesis of methylpyridines from acetaldehyde and ammonia in the presence of heterogeneous Pd complexes containing S is studied by a pulsed microcatalytic method.The process occurs with selective formation of 4-methylpyridine.The difference in the catalytic activity of the studied complexes is explained on the basis of 13C NMR spectra.

Gas-Phase Chemistry of Transition Metal-Imido and -Nitrene Ion Complexes. Oxidative Addition of N-H Bonds in NH3 and Transfer of NH from a Metal Center to an Alkene

We report here on the gas-phase chemistry of a number of bare transition metal-nitrene and -imido ion complexes, MNH+.Group 3, 4, and 5 atomic metal ions react with NH3 at thermal energies to generate MNH+ via dehydrogenation.A reaction mechanism is proposed involving initial oxidative addition to an N-H bond, in analogy to mechanisms proposed for reactions of gaseous atomic metal ions with hydrocarbons.Cr+ reacts with NH3 via slow condensation to form CrNH3+, as do all group 6-11 atomic metal ions investigated.However, excited-state Cr+ reacts with NH3 via bond-insertion reactions to form CrNH2+ and CrNH+.An unidentified metastable electronic state of Cr+, produced by direct laser desorption of chromium foil, reats with much higher efficiency than does kinetically excited Cr+.FeO+ reacts with NH3 to generate FeNH+ with loss of H2O.Thermochemical studies of VNH+ and FeNH+ involving ion-molecule reactions indicate values of D0(V+-NH) = 101 +/- 7 kcal/mol and D0(Fe+-NH) = 54 +/- 14 kcal/mol, the latter value in accord with D0(Fe+-NH) = 61 +/- 5 kcal/mol obtained from photodissociation.The high bond strength for VNH+ indicates multiple bonding, analogous to that in the isoelectronic VO+, while the weaker bond strength for FeNH+ indicates a single bond, analogous to that in the isoelectronic FeO+.Proton-transfer experiments indicate PA(VN) = 220 +/- 4 kcal/mol from which ΔHf(VN) = 111 +/- 9 kcal/mol and D0(V-N) = 125 +/- 9 kcal/mol are obtained.VNH+ is unreactive with ethene and benzene, but FeNH+ transfers NH to ethene and benzene through metathesis and homologation reactions.A cyclic metalloaminobutane intermediate is consistent with the products of the FeNH+/ethene reaction.

The Microwave Spectrum of (Z)-Ethanimine

The microwave spectrum of ethanimine, CH3CH=NH, has been measured over the range of 18-76 GHz.A series of lines have been attributed to the Z-isomer.These have been fitted to an asymmetric rotor with inclusion of centrifugal distorsion parameters.An excited torsional state has also been assigned and the barrier to internal rotation of the methyl group has been determined.The dipole moment has been evaluated from the Stark effect as 2.42 D. The quadrupole coupling constants of the nitrogen atom have been obtained from high-resolution studies.In contrast to methanimine, we found no evidence of magnetic hyperfine interaction in the structure of the multiplets.
