Modules for Acetylenic Scaffolding

Abstract

Polyethynylated ethenes, allenes, butatrienes, ethanes, and methanes provide an outstanding library of versatile modular building blocks for carbon-rich acetylenic scaffolding, targeting one-, two-, and three-dimensional architectures. Many of these modules are today available from straightforward and high-yielding synthetic protocols.
