摘要

而均相钼催化通常促进烯烃与过氧化物的环氧化，在这里，钼双（二噻吩）化合物被证明代替催化氧化烯烃裂解，产生类似于臭氧分解反应的羰基产物。在DFT计算的支持下，提出了氧从Mo(O)（η - 2-O2）中间体向烯烃转移形成1,2-二氧乙烷的机理。

Flash Communication: Unexpected Oxidative Alkene Cleavage Behavior of a Molecular Molybdenum Bis(dithiolene) Catalyst

Whereas homogeneous molybdenum catalysis typically promotes alkene epoxidation with peroxide oxidants, here, a molybdenum bis(dithiolene) compound is shown to instead catalyze oxidative alkene cleavage, resulting in carbonyl products akin to ozonolysis reactions. A mechanism involving O₂ transfer from a Mo(O)(η²-O₂) intermediate to the alkenes to form 1,2-dioxetanes is proposed with support from DFT calculations.

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
