Chemisorbed Benzoate-to-Benzene Conversion via Phenyl Radicals on Cu(110):Kinetic Observation of Conformational Effects

摘要

Free radical intermediates are crucially important in heterogeneous catalysis.Such species are short-lived and difficult to observe.In this communication,we report the thermal generation of phenyl radicals on a surface as well as conformational effects in their abstraction of hydrogen atoms from neighbor molecules containing C-H bonds.
