Electrophilic catalysis of N-- > 0 phosphyl migration
摘要:
2-N-Benzoyl-N-phenylamino-2-oxo-5, 5-dimethyl-1, 3, 2-dioxaphosphorinane (3a) undergoes rearrangement to (2-oxo-5, 5-dimethyl-1, 3, 2-dioxaphosphorinanyl) (N-phenyliminobenzoyl) oxide (4a). This transformation is shown to be catalysed by electrophilic reagents such as benzoyl chloride, trimethylsilyl chloride, p-toluenesulphonyl chloride.

Solvolysis of mixed phosphoric-carboxylic N-phenylimides occurs with exclusive attack of nucleophilies at the carbonyl carbon centre and is accompanied by phosphoryl N->O migration.
