Su. Pandya et al., Addition of functional vinylzinc reagents to nitrones: synthesis of (E)-N-allylhydroxylamines and their rearrangement into (E)-O-allylhydroxylamines, CHEM COMMUN, (18), 2001, pp. 1806-1807
The vinylzinc reagents derived from hydrozirconation of alkynes and transme
tallation add readily to nitrones to yield pure (E)-N-allylhydroxylamines;
some of these rearrange into O-allylhydroxylamines.
