The synthesis of cyclic structures based on acetylene systems has important applications in the formation of nanostructures, naturally occurring compounds and chemosensory materials for the design of nonlinear optics, electronic and photonic devices. Alkynes in Cycloadditions presents a modern review of regioselective synthesis of aromatic and non-aromatic carbocyclic and heterocyclic ring systems based primarily on [2+2+2] and [4+2] cAlkynesRing formation (Chemistry)Alkynes.Ring formation (Chemistry)547/.413Maretina Irina A1609214Tebby John C.1933-99393Ionin B.
