Spectroscopic Signature of the Carbon–Carbon Coupling Reaction between Carbon Monoxide and Nickel Carbide

Spectroscopic characterization of carbon monoxide activation by neutral chromium carbides

“…Recently, the NiC(CO) n − ( n = 3–5) anions were prepared and studied by photoelectron spectroscopy, highlighting the pivotal roles played by metal carbides in C–C bond formation. 30 The study of the reaction between neutral transition metal carbides and carbon monoxide at the molecular level has been proven to be a challenging experimental target due to the difficulty in mass selection. Here, we synthesized neutral chromium carbide carbonyl compounds in a laser vaporization cluster source and measured the infrared spectra of CrC 3 (CO) 2 and CrC 4 (CO) 2 by infrared-vacuum ultraviolet (IR-VUV) spectroscopy.…”
