Thermolysis and photolysis of bifunctional initiators: Free radical centers beta to the azo, azoxy and perester groups
Peresters $\beta$ to azo or azoxy groups are potentially interesting bifunctional initiators. They decompose thermally at essentially the same rate as the analogous simple perester. It follows that decomposition occurs ...
I. Dissociation and aromatization of a semibenzene. Reactions of triphenylmethyl and methyl isobutyryl radicals. II. The chemistry of alpha- and beta- azo radicals
Part I. Semibenzene methyl 7,7-diphenyl-p-mentha-1(7),2,5-triene-8-carboxylate (1), which can be regarded as the para recombination product of triphenylmethyl and methyl isobutyryl radicals (5), affords exactly these ...
The reaction of azoalkanes with radical cation salts
While azoalkanes are normally employed as convenient sources of radicals and biradicals, radical cation salts such as tris-(4-bromophenyl)aminium hexachloroantimonate and thianthrenium perchlorate oxidize azoalkanes under ...
A cycloaddition-based fullerene assembly mechanism
Since their discovery, the fullerenes have challenged scientists with a wide array of problems concerning their properties, behavior and potential applications. One such fundamental question is that of the assembly of these ...
Photolysis of azoalkanes. Reactions and kinetics of the 1-cyclopropyl-1,3-cyclopentanediyl biradical and 1-cyclopropylcyclopentyl radical
The 1-cyclopropylcyclopentyl radical (114a) and 1-cyclopropylcyclohexyl radical (114b) were generated in the presence of PhSH via 366 nm photolysis of azo-1-cyclopropylcyclopentane and azo-1-cyclopropylcyclohexane respectively. ...
Investigation of multiple quantum coherence transfer in two-dimensional NMR spectroscopy
The limitations of zero quantum NMR pulse sequences reported in the literature are discussed. Several new pulse sequences which improve and extend the scope of the currently available pulse sequences are described. A ...
