Sharpless et al. have described, while performing the molybdenum-catalyzed epoxidation reaction of olefins using alkyl hydroperoxides, that the molybdenum-oxo moiety is an active catalytic species. Thus, continuous efforts have been made to synthesize molybdenum-oxo complexes of different ligand environments. While plenty of such works on molybdenum porphyrins are reported in the literature, related molybdenum corroles are very less reported. The synthesis and characterization of two new oxo-molybdenum(V)-corrolato complexes are described herein. Both the complexes have been fully characterized by several spectroscopic techniques in conjunction with single-crystal X-ray diffraction analysis. The efficacy of the oxo-molybdenum(V)-corrolato complexes for the catalytic epoxidation reaction of olefins with the help of hydroperoxides has also been explored. The catalytic application of oxo-molybdenum(V)-corrolato complexes in the epoxidation reaction has not been reported earlier. A mechanism has been proposed to explain the experimental findings.

环氧-钼（V）-Corrolato配合物的合成，表征及在环氧化反应中的应用。

Sharpless等。已经描述了在使用烷基氢过氧化物进行烯烃的钼催化的环氧化反应时，钼-氧代部分是活性催化物质。因此，一直在努力合成不同配体环境的钼-氧配合物。尽管在文献中已报道了大量有关钼卟啉的此类研究，但有关钼钼的报道却很少。本文描述了两种新的氧代-钼（V）-Corrolato配合物的合成和表征。两种配合物均已通过多种光谱技术结合单-晶体X射线衍射分析。还探索了氧-钼-（V）-Corrolato配合物借助氢过氧化物催化烯烃催化环氧化反应的功效。氧-钼（V）-Corrolato配合物在环氧化反应中的催化应用尚未见报道。已经提出了一种机制来解释实验结果。
