Activation of the C-H Bonds in Neopentane and Neopentane-d12 by (.eta.5-C5(CH3)5)Rh(CO)2: Spectroscopic and Temporal Resolution of Rhodium-Krypton and Rhodium-Alkane Complex Intermediates
“…Characterisation of the C-H activation of an organometallic alkane complex in solution by TRIR spectroscopy was achieved shortly afterwards through the monitoring of the photolysis of Rh(Cp*)(CO) 2 in liquid krypton doped with neopentane at low temperature [42]. Additional room temperature TRIR experiments have shown that photolysis of Rh(Cp)(CO) 2 in cyclohexane leads to the formation of Rh(Cp)(CO)(alkane) prior to C-H activation occurring [43].…”

“…Upon photolysis an equilibrium is observed between Cp * Rh(CO)Kr and Cp * Rh(CO)(r-neopentane). The latter undergoes thermal rearrangement to Cp * Rh(CO)(H)(C 5 H 11 ) [62]. Additional studies have established that the character of the alkane has an influence on the rate of oxidative addition.…”

“…Research on the same molecule in inert liquid rare gases, 6 where there are some solvent interactions, but where there can be no chemical reactions, shows the prompt formation of a solvent complex. Further studies have shown that, in dilute solutions of alkanes in rare gas liquids, these rare gas molecules can exchange with alkane molecules to form a C-H-activated final product.…”
