Abstract The substituted pyrroles and dipyrroles along with diacetylenes and cumulenes have been synthesized in high yields using a new synthetic method under mild reaction conditions using the Glaser coupling reaction. Although diacetylenes are formed from 2‐propargyl‐1,3‐dicarbonyl compounds having electron‐donors substituents such as Ph or OEt, only polyfunctional substituted cumulenes are formed from those compounds under the modified conditions. © 2006 Wiley Periodicals, Inc.
