Oxidation of Carbanions

The Carboxylation and Oxygenation of Ribulose 1,5-Bisphosphate: The Primary Events in Photosynthesis and Photorespiration

“…Given the propensity for carban ions to undergo reaction with oxygen (70,167) and fr om what we know about the carboxylase reaction (see discussion above), the most probable fi rst step in the oxygenase reaction is the fo rmation of the enediol(ate) (step 1). Addition of O2 to the enediol(ate) and electron transfer (steps 2 and 3) creates the radical pair, the radical at C-2 of RuBP and the superoxide radical anion.…”

Intramolecular nucleophilic participation. V. The role of the ortho-substituent in the solvolysis of o-nitrobenzhydrl bromide and o-nitrobenzyl tosylate

“…4 An attempt has been made previously to explore the possibility that the nitro group may participate in solvolysis reactions of o-nitrobenzhydryl bromide. 5 Until the present investigation a crystalline sample of this bromide has not successfully been prepared. In the earlier study5 the crude oily product of the reaction of N-bromosuccinimide with o-nitrodiphenylmethane was employed (as the o/7/zo-substituted isomer) in comparing the hydrolysis rates of o-and p-nitrobenzhydryl bromides.…”

Degradation of 1,5-anhydroribitol and 1,5-anhydroxylitol by oxygen in aqueous sodium hydroxide solutions

“…reaction (10) would be expected to have essentially a zero activation energy [38][39][40] Thus, once A. is formed it would react very rapidly with oxygen in its vicinity.…”
