Arylphosphoester → Phenol derivative<br>Arylphosphodiester → Phenol derivative + Phosphoester<br>Arylphosphotriester → Phenol derivative + Phosphodiester<br><br>Comments:<br>This rule is also triggered by vinylphosphoesters. The enol product of vinyl phosphate substrates rapidly tautomerizes to the more stable keto form. This rule handles the enol-keto tautomerization.
