Improved reagent for electrophilic amination of stabilized carbanions.
[reaction: see text]. Enolate amination using O-di(p-methoxyphenyl)phosphinylhydroxylamine 2 is reported. Reagent 2 reacts efficiently with stabilized sodium or potassium enolates derived from malonates, phenylacetates, and phenylacetonitriles and is sufficiently soluble for use in solution at -78 degrees C.
