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

Formation and reactivity of organometallic alkane complexes

“…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].…”

Organometallic photochemistry at the end of its first century

“…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.…”

Ultrafast Infrared Studies of Bond Activation in Organometallic Complexes

“…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.…”
