A general, mild, and efficient reductive cleavage of aryl O-carbamates to phenols using the Schwartz reagent is selective and tolerates a large number of functional groups. The cleavage may be carried out by direct or by an economical in situ procedure; and, notably, establishes a synthetic connection to the directed ortho metalation strategy.
