Radicals used as spin probes can provide important information on structures and conformational changes of calixarenesthrough inclusion complexes of radicals or spin labels. Multispin-labeled calixarenes and polyradicals based calixarene skeletonsshould provide chances to study magnetic interaction and develop potential applications. In the present review, recent progresses inchemistry of calixarene and free radicals are described.

A novel 1,2,3-triazolyl-linked8-hydroxyquinoline dimer as a highly selectiveturn-on fluorosensor for Cd2+
over a range of other metalions, including Zn2+, wasefficiently synthesized fromthe “click” reaction andshowed weak fluorescencein protic solvents.

An intermolecular nickel-catalyzed [4 + 2] cycloaddition has been developed wherecarbonylsalicylamides react with alkynes to afford substituted chromones. The reactioninvolves an elimination of isocyanates and an addition of alkynes, that is, a formalsubstitution reaction of an isocyanate by an alkyne.
