    • In the absence of the phosphine ligand another mechanism may take place involving protonolysis as a product formation step (Scheme 2). See reference [3] for discussion of various mechanistic details. In any case, alkyne coordination and insertion remain as the key steps in all reported reactions.

    • In addition to product 3a (≈50%) the formation of 1,3-dienes was also observed according to a known reaction. Both reactions-formation of alkene 3 a and dienes-involve alkyne insertion and re- ductive elimination steps (see ref. [22] for the discussion of the mechanism of dienes formation).

    • note
    • [12,17,19] At the moment it is impossible to separate unambiguously these two types of the ligand effects and to estimate their contribution to the overall performance enhancement of the studied catalytic reaction. In any case, it is clear that the pathway involving alkyne coordination to the apical Ni site without the need of phosphine ligand dissociation better agrees with the results of the NMR monitoring.
