Conclusions

  1. 1.

    The ionization potentials of (CH3)3CC≡CR (R=H, CH3, C(CH3)3, 1-Ad, C6H5, COOCH3, CN, CF3) are in qualitative accord with the electron-donor or electron-withdrawing properties of these substituents. The adamantyl group is a better electron donor than the (CH3)3C group.

     
  2. 2.

    The enthalpies of formation of the ions from (CH3)3CC≡CR do not correspond to the propargyl structure\((CH_3 )_2 \mathop C\limits^ + C \equiv CR\) but rather characterize substituted cyclopropenyl ions.
