A simple catalytic method involving all‐metal aromatic frameworks as precatalysts ensures an efficient route to (Z)‐alkenes. Aromatic triangular palladium clusters were used to reduce internalalkynes without any trace of the formation of alkane side products. These trinuclear complexes provide a catalytic system that parallels the activity and selectivity of their best mononuclear peers, and the catalyst
efficient catalytic approach to the synthesis of N,N-dialkyl-2-alkynylanilines was developed by using Pd-catalyzed norbornene-mediated three-component reactions of haloarenes, alkoxyamines (RO-NR2), and alkynes. The procedure forms one CN bond and one CC bond efficiently in a one-pot manner from readily available starting materials. A number of 2-alkynylanilines with a broad range of functional groups
