Abstract
Calculations for HC≡CH, HC≡CCF3, and H3CSC≡CCF3 were carried out using the MP2(f)/6-31G(d) nonempiric quantum-chemical method. The electronic structure and charge density distribution were examined using natural bond orbitals and the results account for the differences in the direction of nucleophilic attack of the triple bond in HC≡CCF3 and H3CSC≡CCF3.
