Palladium-catalyzed regio- and stereoselective alkoxycarbonylation of unsymmetrical internal alkynes toward α, β-unsaturated succinates

HIGHLIGHTS

• who: Chang-Sheng Kuai from the Dalian National Laboratory Sciences, Dalian, China University of have published the Article: Palladium-catalyzed regio- and stereoselective alkoxycarbonylation of unsymmetrical internal alkynes toward u03b1, u03b2-unsaturated succinates, in the Journal: (JOURNAL)
• what: And discussion At the outset of the work , the authors employed ethanol and phenylpropiolate as the model substrates, Pd(PPh3)4 and PTSA as the catalytic system under CO pressure (10 bar) in THF at 100 C. First, a variety of ligands were evaluated .
