and phenylacetylene has become a base chemistry platform for several on-going projects as well as new development projects and alternative chemistry routes for existing products.
Alkynes have become core building blocks for several other functionalized products such as our specialty olefins, diactylenic intermediates and specialty heterocycles, to name a few. We estimate that alkyne chemistry is respon- sible for approximately 15% of all R&D work today. The growing number of literature references that use acetyle- nic intermediates in organic synthesis demonstrates the impact this chemical fam- ily continues to have on the research community from "Click Chemistry"®
