(18) In 2, the boron atoms are located in the shielding cone of
the C≡C triple bond (cf. (11B) in C6D6: 2 = 53 ppm, 9 = 73 ppm).
Care must be taken not to overestimate the extent of THF ligation in 2
on the basis of the (11B) value recorded for this compound in THF-
d8. We therefore believe that THF ligation is mainly relevant for 1
(and here for its redox potential).
(19) Also for the Me derivative 4, a dynamic equilibrium close
to 90% conversion cannot be excluded, but the size of the effect is
likely already beyond the limits of measurement error.

(21) The conversion of the sodium salt Na2[2] to Na2[2-H2] is
quantitative after 93 h at 100 °C. Thus, not only the stability of the
[2]2– ion but also the nature of the counter cation is an important
factor.
