Abstract: Tandem bis‐alkoxycarbonylation of alkynes allows for the preparation of 2‐substituted succinates from alkynes and nucleophile alcohol via two successive alkoxycarbonylation with advantages of 100 % atomic economy and simplified one‐pot operation. Herein, the one‐pot tandem bis‐alkoxycarbonylation… read more here.

Abstract: A bi-functional ligand (L1) containing a diphosphino fragment and sulfonic acid group (–SO3H) enabled PdCl2(MeCN)2 to efficiently catalyze the tandem bis-alkoxycarbonylation of terminal alkynes to produce aryl-/alkyl-substituted succinate (α,ω-diesters). It was found that the –SO3H… read more here.
