Alkynes in Cycloadditions.
Acetylene systems present a new route to cyclic compounds as an alternative tomore traditional methods employed in classical organic chemistry. The synthesis of cyclic structures based on acetylene systems has important applications in the formation of nanostructures, naturally occurring compounds a...
