Abstract
We report on the reactivity of grafted tantalum organometallic catalysts with molecular oxygen. The changes in the local Ta electronic structure were followed by in situ high-energy resolution off-resonant spectroscopy (HEROS). The results revealed agglomeration and formation of Ta dimers, which cannot be reversed. The process occurs independently of starting grafted complex.

We report on the reactivity of grafted tantalum organometallic catalysts with molecular oxygen
Thanks to the scanning-free arrangement, the high-energy resolution off-resonant spectroscopy (HEROS) spectra can be recorded with a sub-second time resolution and with an energy resolution being independent of the initial state lifetime broadening.[9]
