Carbon–carbon coupling from formaldehyde reaction on Mo(110)

Formaldehyde (CH 2O) reaction on Mo(110) is studied with temperature programmed reaction and infrared reflectance absorbance spectroscopy. We present preliminary results which demonstrate the evolution of gas-phase ethylene from the formaldehyde reaction, to the best of our knowledge the first examp...

Description
Summary:Formaldehyde (CH 2O) reaction on Mo(110) is studied with temperature programmed reaction and infrared reflectance absorbance spectroscopy. We present preliminary results which demonstrate the evolution of gas-phase ethylene from the formaldehyde reaction, to the best of our knowledge the first example of carbon–carbon bond formation on clean Mo(110). This reaction is proposed to proceed via an ethylene dialkoxide intermediate, analogous to that formed during reaction of ethylene glycol on Mo(110). Other reactions include hydrogenation of CH 2O to form a methoxy intermediate which subsequently undergoes C–O bond scission to evolve gas-phase methyl radicals at ∼600 K.
