[12] To the best of our knowledge, selective cross-dimerization of two differ-
ent terminal alkynes to produce head-to-tail-fashioned enynes has been
reported by only two groups; one uses an Rh catalyst and the other uses
Pd, see: a) H.-D. Xu, R.-W. Zhang, X. Li, S. Huang, W. Tang, W.-H. Hu, Org.

[13] For entries 1 and 2 in Tables 1 and 2, unreacted substrates remained
in the crude states, and a minor amount of a ketone byproduct was
observed.

[14] The use of 1 as a catalyst yielded 17 in 83 % yield with a trace amount
of iso-17 and a mixture of 19/iso-19 in 59 % yield in a ratio of 93:7; see
ref.[5]
[15] Mechanistic details of this temperature-based isomerization are not yet
fully known.

[8] Very small resonances of the plausible “in-in” compound were found in
the 1H NMR spectrum of the crude material, and this “in-in” compound
was readily removed.
