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.) .

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.

Aminohydroxy anion (3), dissociated species of hydroxylamine, was demontrated to be nucleophilic on oxygen atom from INDO calculation, and to give directly O-alkylhydroxylamines.
