Conclusions

  1. 1.

    The optimum conditions for conducting coupling reactions of terminal acetylenes with organic halides in the presence of amines, CuI, and palladium complexes were determined.

     
  2. 2.

    Pd(0)-Pd(PPh3)2 and Pd (II)-R'PdX (PPh3)2 complexes are intermediates in the catalytic reactions of RC≡CH with R'X(“Pd,” Et3N, CuI).
