    • The potential energy surface of rotation around the single carbon-carbon bond of the 1,3-diene is characterized by two minima with a C=C-C=C angle of 180° (s-trans conformation) and 38° (s-gauche conformation). The s-cis conformation with a C=C-C=C angle of 0° is a transition state; the second transition state is located at 102°. The s-trans conformation is thermodynamically the most stable. See:(a) Wiberg, K. B.; Rablen, P. R.; Marquez, M. J. Am. Chem. Soc. 1992, 114, 8654.

    • Several experimental studies have shown that insertion of terminal alkynes into the M-E bond (E, S, Se) is highly regioselective and leads to M-CH=C(R)E species, while the formation of M-CR=C(H)E species was not observed see ref 5, Therefore, this pathway was not examined in our theoretical study

    • The calculations were carried out using the B3LYP density functional level with the Stuttgart/Dresden ECP basis set on the metal and the 6-311G(d) basis set on the other elements (see the Supporting Information for a complete description). In the previous studies it was established that this level of theory reasonably well describes the energy and geometry parameters of the systems involving transition metal complexes:(a) Ananikov, V.

    • There are two possible reasons for the observed stability of the s-gauche conformation: (1) thermodynamic reasons; for the synthesized dienes the s-gauche conformation is lower in energy than s-trans; and (2) kinetic reasons; the high energy barrier of rotation around the central C-C bond. The key difference between dienes 2 and 3 is the presence of substituent R in the 3-position of 2, which should enhance the influence of both above-mentioned factors.
