Abstract

It is well known that structural motifs with carbon–carbon triple bonds have prevailed in many bioactive compounds, natural products, pharmaceuticals, and functional materials. 1 Since the late 20th century, the Sonogashira reaction has been proved to be an effective approach for the synthesis of various alkynes. 2 The typical Sonogashira coupling is performed in the presence of PdCl 2 (PPh 3 ) 2 or Pd(PPh 3 ) 4 together with CuI as the cocatalyst and larger amount ...
