Cis all round: Dichlorobis[1‐(dicyclohexylphosphanyl)piperidine]palladium, [(P(NC5H10)(C6H11)2})2Pd(Cl)2], is a highly efficient alkynehydrothiolation catalyst and the first generally applicable system that selectively generates cis‐configured anti‐Markovnikov adducts in excellent yields within only a few minutes at 120 °C in the presence of only 0.05 mol % of the catalyst (see scheme).
全面顺产:二氯双[1-(二环己基膦酰基)哌啶]钯,[[P (NC 5 H 10)(C 6 H 11) 2 }) 2 Pd(Cl) 2 ]是一种高效的炔烃加氢硫基化催化剂,第一个普遍适用的系统,仅在0.05 mol%的催化剂存在下,在120°C的情况下,仅需几分钟即可选择性地以优异的收率生成顺式构型的反马氏复合物(见方案)。

efficient catalytic system based on easily available palladium acetate was developed for the selective addition of aliphatic thiols to the triple bond of internal alkynes. Formed in situ [M(SR)2]n nanostructured particles were found to be an active form of the catalyst. It was experimentally confirmed for the first time that the most active form of the catalyst for thiol addition to internal alkynes is formed
