Relationship between isotopic scrambling and mechanism in labeled ion molecule reactions: The reaction ofCH3plus;with CH4

摘要

The isotopically mixed products of the reaction ofCH3plus;with CD4andCD3plus;with CH4are analyzed in terms of the reaction mechanism. It is concluded that the products are not randomly distributed, and that three separate and distinguishable reaction channels may be operative with H2elimination from the initial ionic carbon the most likely channel. No intermediate is invoked to explain the observed results, and it is shown that significant Hsngbnd;D scrambling during the reaction is not necessary to account for the isotopically mixed products observed.
