Following CO and H Insertion into Ru–C Bonds with X-ray Photoelectron and Absorption Spectroscopies
Insertion reactions play a central role in the catalytic synthesis of ethanol and higher alcohols. X-ray photoelectron and absorption spectroscopies have been used to follow migratory CO insertion and C─C coupling in a <i>cis</i>-[Ru(2,2'-bipyridine)<sub>2</sub>(CO)(CH<sub>3</sub>)]<sup>+</sup> complex heated in a vacuum or exposed to CO. Heating of the Ru complex in a vacuum to temperatures above 50 °C induced spontaneous migration of CO into the Ru─CH<sub>3</sub> bond to yield a ─COCH<sub>3</sub> ligand. After adding CO to the background gas, the CO insertion reaction was seen at room temperature, opening the door for the synthesis of ethanol and more energy dense liquids.
