Continuous multistep synthesis of 2-(azidomethyl)oxazoles

open access: yesBeilstein Journal of Organic Chemistry, 2018
An efficient three-step protocol was developed to produce 2-(azidomethyl)oxazoles from vinyl azides in a continuous-flow process. The general synthetic strategy involves a thermolysis of vinyl azides to generate azirines, which react with bromoacetyl ...

Polarographic Determination of Vinyl Compounds

open access: yesBUNSEKI KAGAKU, 1955
Polarographic determination of several vinyl compounds have been investigated with the use of tetramethylammonium ion, (CH3)4N+, and tetrabutylammonium ion, (C4H9)4N+, as the supporting electrolytes. The vinyl esters, such as vinyl acetate, vinyl butylate, and vinyl benzoate, can be determined from the wave of acetaldehyde which is produced by the ...

Insoluble polyelectrolyte and ion-exchange hollow fiber impregnated therewith [PDF]

open access: yes, 1977
The number of quaternary sites and ion exchange capacity of a polyquaternary, cross linked, insoluble copolymer of a vinyl pyridine and a dihalo organic compound is increased by about 15-35% by reaction of the polymer with an amine followed by ...

Palladium Catalyzed Reactions of 2-Nitroaniline with Vinylethers

open access: yesE-Journal of Chemistry, 2007
A new method for the synthesis of hemiaminal ether have been suggested. The reactions of 2-nitro aniline with vinyl ether in the presence of PdCl2(CH3CN)2 produces hemiaminal ether compounds. The resulting products have been identified by spectral data.
