Static Protonated and Exchanging Diprotonated Ambivalent Heteroorganic Systems: Hydroxylamines, Acetone Oxime, and Dimethyl Sulfoxide

چکیده
Monoprotonated aliphatic hydroxylamines, acetone oxime, and dimethyl sulfoxide as their fluoroantimonate salts (prepared from the corresponding hydrochloric acid salts) in SbF5-SOzClF (or SOz) solution were studied to determine the site of protonation. Subsequently, diprotonation was also investigated in HSOsF-SbFs (magic acid) solution. From the 'H and 13C NMR data of the static and exchanging species it was possible to determine the site of monoprotonation, as well as an indication of diprotonation. MINDO/3 calculations were also carried out on the parent, mono-, and diprotonated forms of dimethyl sulfoxide. The calculated and experimental results gave good agreement.

Decryptification of acid phosphatase in arthrospores of Geotrichum species treated with dimethyl sulfoxide and acetone.
Decryptification of acid phosphatase in Geotrichum sp. arthrospores was accomplished using acetone or dimethyl sulfoxide treatment. Both dimethyl sulfoxide and acetone irreversibly destroyed the integrity of the spore membranes without solubilizing acid phosphatase.
متن کاملA thermodynamic and kinetic characterization of the solvent dependence of the saddle-crown equilibrium of cyclotriveratrylene oxime.
The equilibration of the saddle conformer of cyclotriveratrylene (CTV) oxime to the corresponding crown conformer was followed by (1)H NMR in five separate solvents, and kinetic and thermodynamic parameters were determined from the NMR data. The oxime saddle conformers of 3 are favored in CDCl(3) (K(eq) = [saddle]/[crown] = 1.4), whereas the CTV oxime crown conformer 3a is favored in three more...
متن کاملIdentification of the sulfoxide functionality in protonated analytes via ion/molecule reactions in linear quadrupole ion trap mass spectrometry.
A mass spectrometric method utilizing gas-phase ion/molecule reactions of 2-methoxypropene (MOP) has been developed for the identification of the sulfoxide functionality in protonated analytes in a LQIT mass spectrometer. Protonated sulfoxide analytes react with MOP to yield an abundant addition product (corresponding to 37-99% of the product ions), which is accompanied by a much slower proton ...
متن کاملInteraction of acetonitrile with trifluoromethanesulfonic acid: unexpected formation of a wide variety of structures.
Interaction of acetonitrile with trifluoromethanesulfonic acid has been studied by multinuclear NMR and ESI-MS. It has been found that the interaction results in formation of a great variety of different cations and neutral compounds which is controlled by the ratio of CH(3)CN to TfOH. In the presence of an excess of the acid (molar ratio 1 : 8-14) diprotonated N-acetylacetamidine 1 is formed a...
