title: Encapsulated reagents for nitrosation.
abstract: [reaction: see text] A novel class of stable, mild, and size-shape-selective nitrosating agents for secondary amides is introduced. These are based on reversible entrapment and release of reactive nitrosonium species by calix[4]arenes. The NO(+) encapsulation controls the reaction selectivity.
