Allyl radicals from 3,3′-azo-1-propene

Preparation of 1-C14-propene-1 and the mechanism of permanganate oxidation of propene.

. l-C14_propene~1 has been prepared. The migration of the double bond under a variety of experimental conditions in the preparation of propene has been investigated. 'rhe mechanism of the permanganate oxidation of the labelled propene has been examined; it has been found to proceed by several paths, the relative importance of which depends upon the experimental conditions .. especia lly the pH....

Competing sigmatropic shift rearrangements in excited allyl radicals.

The competition between rearrangement of the excited allyl radical via a 1,3 sigmatropic shift versus sequential 1,2 shifts has been observed and characterized using isotopic substitution, laser excitation, and molecular beam techniques. Both rearrangements produce a 1-propenyl radical that subsequently dissociates to methyl plus acetylene. The 1,3 shift and 1,2 shift mechanisms are equally pro...

1-Allyl-2-amino­pyridin-1-ium bromide

In the cation of the title salt, C8H11N2 (+)·Br(-), the dihedral angle between the planes of the pyridinium ring and the allyl group is 79.4 (3)°. In the crystal, N-H⋯Br and weak C-H⋯Br hydrogen bonds link the cations and anions, forming chains of alternating R 2 (1)(7) and R 4 (2)(8) rings, which run parallel to the c-axis direction. The crystal studied was an inversion twin with components in...

New copolymer of acrylamide with allyl methacrylate and its capacity for the removal of azo dyes

The copolymerization reactions of Acrylamide (AA) with the different mole ratios of allyl methacrylate (AMA) such as 25/75, 50/50 and 75/25 were studied by radical polymerization under argon atmosphere using 2,2’-Azobis (isobutyronitri1e) (AIBN) as initiator. The copolymers were characterized with Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG). FTIR spectra s...
