Graphene oxide as a metal-free catalyst for oxidation of primary amines to nitriles by hypochlorite
Graphene oxide catalyzes oxidation by NaClO of primary benzyl and aliphatic amines to a product distribution comprising nitriles and imines. Nitriles are the sole product for long chain aliphatic amines. Spectroscopic characterization suggests that percarboxylic and perlactone groups could be the active sites of the process.

The Reactivity of Difluorocarbene with Hydroxylamines: Synthesis of Carbamoyl Fluorides
Carbamoyl fluorides are formed in reactions of hydroxylamines with difluorocarbene generated from sodium bromodifluoroacetate as readily available and non-toxic carbene precursor. The process shows a high functional group tolerance, and the reaction path has been rationalized by computational calculations. (Figure presented.) .

Mechanism of the 10-methylacridinium ion-sensitized photooxidation of N,N-dibenzylhydroxylamine and its derivatives in acetonitrile
The 10-methylacridinium ion (MA+)-sensitized photooxidation of substituted N,N-dibenzylhydroxylamines (1) in acetonitrile occurred mainly by a superoxide ion mechanism to give N-benzylidenebenzylamine N-oxides (2) and hydrogen peroxide quantitatively. Analysis of substituent effects on the limiting quantum yield for formation of 2 showed that back electron transfer (ET) from the 10-methylacridinyl radical (MA.) to the radical cation 1+. proceeds in the Marcus 'normal region'. In addition, this back ET was found to take place in preference to one-electron reduction of O2 by MA..

Imine-forming radical elimination reactions of O-(1-naphthoyl)-N,N- bis(p-substituted benzyl)hydroxylamines activated by triplet benzophenone
It was shown that despite the occurrence of a diffusion-limited triplet energy transfer between the title hydroxylamine 1 and benzophenone, triplet 1 decomposed inefficiently giving p-substituted N-(p-substituted benzylidene)benzylamine 2 and 1-naphthoic acid (3) as unimolecular radical elimination products. The logarithm of the k(r)/k(d) ratio (where k(r) is the rate constant for homolytic cleavage of the N-O bond in triplet 1 and k(d) is that for its deactivation) used as a measure of the triplet-state reactivities of 1, showed a negligible dependence on the substituent constant. This finding was explained in terms of a very small contribution of the ionic structure to the transition state for the N-O bond homolysis.
