Lewis-base-catalysed selective reductions of ynones with a mild hydride donor
Sch?mberg,Zi,Vilotijevic

Ynones are efficiently reduced with a mild hydride donor in the presence of a catalytic amount of nucleophilic phosphines. The reactions are selective 1,2-reductions that give propargyl alcohols in yields of up to 96%. It is proposed that success in these reactions depends on the activation of ynones by a Lewis base catalyst. A protic additive plays a key role in suppressing the undesired reaction pathways and accelerating the 1,2-reductions.
NiICatalyzes the Regioselective Cross-Coupling of Alkylzinc Halides and Propargyl Bromides to Allenes

supporting information, p. 1584 - 1590 (2017/02/10)
We describe the unprecedented formation of allenes by Ni-catalyzed cross-coupling of propargyl bromides with alkylzinc halides. The reaction regioselectivity is complementary to the previously reported formation of propargyl-coupled compounds. Experiments
Green synthesis of water-dispersable palladium nanoparticles and their catalytic application in the ligand- and copper-free Sonogashira coupling reaction under aerobic conditions
Nasrollahzadeh, Mahmoud,Maham, Mehdi,Tohidi, Mohammad Mostafa
, p. 83 - 87 (2014/05/20)
Pd nanoparticles were prepared from PdCl2 by green method and were characterized with UV-vis, XRD and TEM methods. Catalytic studies indicated that Pd nanoparticles exhibited high activity for ligand-, amine- and copper-free Sonogashira couplin
