Effect of the electronic structure on hydrogenation of 4-tert-butylphenol on metallic catalysts

Selectivity Engineering and Efficacy of the Ru–Ni@RGO Catalyst in Hydrogenation of p-tert-Butylphenol to p-tert-Butylcyclohexanol

“…Pak and Kartopozhkina discussed different mechanisms that give insight into the possibilities of hydrogenation of PTBP over a catalyst. 2 The formation of PTBP + on the surface occurs with the addition of a hydride ion (H − ) in the first stage of hydrogenation. The C2−C3 and C4− C5 bonds are relatively weakened, but the C2−C3 bond is significantly more activated in this form of adsorption on the catalyst.…”

“…The C5−C6 bond is also slightly weakened, suggesting that the ring could potentially rupture at this bond under corresponding conditions (Scheme 1). 2 Based on this mechanism, we conducted an exploration of the reaction progress using our synthesized catalyst.…”

“…In hydrogenation of PTBP, the benzene ring of the structure is hydrogenated over a catalyst in an acidic medium as there is a probability of hydrogenolysis in the absence of an acidic environment.
