General Description

The chemical formula "CH3CH=NH" represents the organic compound methylamine, which consists of one carbon atom, four hydrogen atoms, and one nitrogen atom. Methylamine is a colorless gas with a strong and unpleasant odor. It is commonly used in the production of pesticides, pharmaceuticals, and rubber chemicals. Additionally, it can be converted into a variety of other chemicals, including methyl isocyanate, which is a key intermediate in the production of carbamate pesticides. Methylamine is also used as a precursor in the synthesis of certain drugs, such as ephedrine and methamphetamine. Due to its potential hazards, including flammability and toxic effects, proper precautions should be taken when handling methylamine.

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.

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.
