The Reactivity of 1,3-Butadiyne Moieties in the 'Exploding' [n]Rotanes-A Crown of Thiophenes

摘要

In recent years, a variety of cyclic, macrocyclic, and oligo-cyclic poly-acetylenes have been prepared. On top of having interesting structural and physical properties, such compounds should show a rich chemistry due to the high reactivity of their acetylene moieties towards electrophiles. nucleophiles. and metal compounds. In particular, molecules with 1.3-diyne units should tend to give interesting new structures upon reaction with various reagents.
