... the two equilibrium and twisted conformational states than that (7.1 × 107 s–1)
at 77 K. The quintet spectrum of the propagating ethylene radical on the PTFE
surface was caused by the high rate of the exchange even at 77 K as shown in

Superelectrophiles and Their Chemistry
... gas-phase studies.24 Although the ethylene dication (1) can be detected in
mass spectrometric experiments by charge stripping of the ethylene radical
cation with molecular oxygen, 1 could not be generated yet in the condensed
phase.

Organic Reaction Mechanisms, 1974
Electron transfer occurs in the reaction of diethyl malonate with copper
isocyanide complexes.775 The tetracyano- ethylene radical anion is generated
as a result of charge transfer between iV,iV-cliethyl- aniline and
tetracyanoethylene.776 ...

The quenching radical can be another growing chain end, an initiator fragment,
or an ethylene radical. Various impurity molecules can prematurely terminate the
growth of a chain, so great care is taken to ensure that all reactants are extremely
...

Progress in Physical Organic Chemistry
For example, the concentration of 1,1-dipheny1 ethylene radical-ions in
equilibrium with the relevant dimeric dianions is less than 10'7M when the
dianions are at about 0.1M concentration (195). Similar results were obtained for
the dimeric ...

BEBOP, a New Reactive Potential Using Bond-energy/bond-order ...
The successful BEBOP(LSDA) description of radical addition reactions was
demonstrated using the addition of a H radical to ethylene. Radical abstraction
reactions were considered by examining the abstraction of H from methane with
OH ...

Computational Molecular Biology
Studies on the cyclobutane radical cation [21,22] showed a low activation energy
for the cycloaddition of an ethylene radical cation to ethylene, in remarkable
contrast with the high activation energy for the corresponding neutral reaction [23
].

The product is the ethylene radical cation. In this case, the loss of a neutral, even
—electron molecule from an even—mass molecular ion leads to a new radical
cation with an even mass. The loss of H2 from the same carbon also occurs as ...
