Free Radicals in Chemistry and Biology
H - C - distance at which the disproportionation reaction takes place corresponds
to the van der Waals contact radius of 0.29 nm, between the carbon of the radical
and the 3-H atom on the neighboring radical.262 Also, atoms other than ...

Handbook of Radical Polymerization
The molecular weight distribution and the polydispersity are functions of the
mode of termination; the polydispersity M w/ Mn is equal to 1.5 if termination is by
combination only, and 2 if by disproportionation only.433 The nature of the end ...

Sulfur Biogeochemistry: Past and Present
Although disproportionation reactions do not cause a net oxidation of the sulfur
species, they have a key function in sulfide oxidation. Disproportionation
provides a shunt in the sulfur cycle whereby the H,S formed by this reaction may
again be ...

Aquatic Geomicrobiology
There are obviously a wide variety of different physiological adaptations to sulfur
compound disproportionation, allowing disproportionation to potentially occur in
a broad range of different environments. Thus, in stable anoxic settings with ...

When toluene undergoes disproportionation under the steric constraints imposed
by medium pore zeolites, p-xylene is the primary product [82]; however an
equilibrium mixture is always attained even at low conversions since the rate of ...

5.7.7.2 Isomerization and Disproportionate of meta-Xylene On catalysts with
Brcnsted acid sites, meta-xylene can undergo isomerization (to para- and orf/io-

Some orientations of the radical pair lead to radical-radical coupling while other
orientations give only disproportionation. The dynamics of radical pair
reorientation phenomena depend on solvent and temperature and calculated (kD
