Migration of the Hydroxyl Group of N-Hydroxy-N-phenylamides to the Phenyl Group with Tertiary Phosphines and Tetrachloromethane. A Novel Transhydroxylation Reaction

Article abstract of DOI:10.1246/cl.1993.1369

The hydroxyl group of N-hydroxyl-N-phenylamides rearranges mainly to the ortho position of the N-phenyl ring by the system (n-Bu)3P-CCl4-CH3CN; use of less than a stoichiometric amount of (n-Bu)3P is effective for this reaction.
