Records ] 引证关系图 | 摘要: Tert-butylation of phenol with tert-butyl alcohol (TBA) over H-beta zeolite was studied using the ONIOM approach with two proposed reaction paths: stepwise and concerted mechanisms. The results obtained by the ONIOM2 (B3LYP/6-31G(d‚p):UFF) method reveals that the tert-butylation of phenol preferentially occurs through a co-adsorbed‚ concerted mechanism without prior dehydration of tert-butyl alcohol‚ rather than via a stepwise mechanism through dehydration to form tert-butyl carbenium
