英文摘要 | metal-carbenes act as the active sites in varieties of important reactions, and in this work, the possible pathways of mo-carbene formation in mo/beta zeolite were explored by density functional calculations. four chiral oxametallacyclobutane intermediates of different energies were determined for either propylene or 2-butylene, corresponding to the four independent reaction pathways. the main products were mo-methylidene for propylene and syn-mo-ethylidene for 2-butylene, respectively. on the basis of energy profiles, the activities of producing the mo-carbene species were found to decrease in the order of propylene > 2-butylene > ethylene, which were the compromising results of electrophilic and steric effects.
