The incorporation of alkynes into organic mols. is one of the most valuable transformations for the formation of C-C bonds and provides a versatile handle for further modifications. The Sonogashira cross-coupling of acetylenes holds a prominent position among the suite of catalytic cross-coupling reactions that are key to modern synthesis. Herein, a method that is complementary to the Sonogashira reaction, demonstrating cross-coupling of lithium acetylides with aryl bromides is presented. The reactions take place under ambient conditions with short reaction times, affording the corresponding aryl acetylenes in good to excellent yields while displaying a remarkable functional group tolerance for an organolithium reaction, allowing the presence of a variety of organolithium-sensitive carbonyl functionalities. This developed cross-coupling methodol. offers ample opportunities to access a wide variety of acetylenes, as is illustrated by the facile preparation of key intermediates for chem. biol. and optoelectronic materials. After reading the article, we found that the author used 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4SDS of cas: 2635-13-4)
Furthermore, the coupling of 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4) with β-methallyl alcohol was catalyzed by Pd(OAc)2 in combination with P(t-Bu)3.SDS of cas: 2635-13-4
