Cyclohexanethiol adsorption and reaction on the Ni(111) surface

Article Abstract:

Research was conducted to examine the cyclohexanethiol adsorption and reaction on the Ni(111) surface. The surface reactions of cyclohexanethiol were characterized on the Ni(111) surface as part of a broader study of C-S bond activation in thiols. The C-S bond in benzenethiol is broken by direct interaction with the nickel surface at 260 K. Results suggest that the mechanism for C-S bond activation is the same for cyclohexanethiol and benzenethiol.

Benzenethiol reaction on the clean and hydrogen pretreated Ni(100) surface

Article Abstract:

A study was conducted to analyze benzenethiol reactions on clean and hydrogen precovered Ni(100) surfaces to examine C-S bond breaking. A stainless steel ultrahigh vacuum chamber was utilized to carry out the temperature programmed desorption and high-resolution electron energy loss spectroscopy studies. Results indicated that C-S bond scission in benzenethiol on the Ni(100) surface supported the formation of benzene at 270 K.

Toluene formation from coadsorbed methanethiol and benzenethiol on nickel surfaces

Article Abstract:

Carbon-carbon bond formation resulting in cross coupling is demonstrated for coadsorbed benzenethiol and methanethiol on the Ni(111) and Ni(100) surfaces. The effect of coadsorbed hydrogen is larger on the Ni(111) surface.
