much greater reactivity of alkynes, compared with the alkenes, towards nucleophilic attack is primarily a transition-state property, reflecting the greater stability of the sp2(compared with sp3)-hybridised carbanions produced. Antiperiplanar addition is probably involved in all these reactions. There is little difference in intrinsic reactivity between 5-exo, 6-exo, and 6-endo-trig olefin cyclisations
