title: "Two functional groups in one package": using both alkyne π-bonds in cascade transformations.
abstract: Spatial orthogonality of the two independently addressable π-systems in alkynes can be used for the design and control of metal-free cascade transformations. Examples include ionic chemistry of neutral hydrocarbons, preparation of radicals without radical initiators, generation of excited states without light, "1,2-dicarbene reactivity" of alkynes in "boomerang" radical processes, selective conversion of alkynes into carbonyl compounds, and full disassembly of the alkyne moiety.
