The difference in [3 + 2] cycloaddition reactivity between fac-
[MO<sub>3</sub>(tacn)]<sup>+</sup> (M = Re, <sup>99</sup>Tc; tacn = 1,4,7-triazacyclononane) complexes has been
reexamined with a selection of unsaturated substrates including sodium 4-
vinylbenzenesulfonate, norbornene, 2-butyne, and 2-methyl-3-butyn-2-ol
(2MByOH). None of the substrates was found to react with the Re cation in
water ...
