Complex-induced proximity effects in proton transfer and halogen-metal exchange reactions
Reactions in which there is formal intramolecular transfer of an acidic deuterium to a site of halogen-lithium exchange could be interpreted to show that initial halogen-lithium exchange occurs faster than loss of the acidic deuterium. However studies of the competition between halogen-metal …

The thermal degradation of polystyrene.
… In a theoretical study the importance of intramolecular transfer during degradation is emphasized in the formation of oligomeric volatiles. To account for past experimental results a mechanism is proposed involving biradical cage combination. The presence of weak links in …

An Investigation of Acetobacter aceti N5-Carboxyaminoimidazole Ribonucleotide Mutase and Its purE-purK Operon
… mutase: PurE) catalyzes the reversible intramolecular transfer of the carboxylate of N5-carboxyaminoimidazole ribonucleotide: N5-CAIR) to the C-4 position of the imidazole ring to form 4-carboxyaminoimidazole ribonucleotide: CAIR). A series of mutants was made to explore the role of two …
