Self-assembled tetranuclear molybdenum(vi) complexes with hydrazonato ligands, [MoO₂L]₄, were tested as (pre)catalysts for cyclooctene and cyclohexene epoxidation without extra organic solvent added. Special attention was addressed to the comparison of oxidizing agents, TBHP in water vs. TBHP in decane. The idea was to test the greenness of the complete process. Density Functional Theory calculations were used to support and explain experimental catalytic result for tetranuclear self-assembled systems.

四核酰肼钼环氧化（预）催化剂：水始终是最佳选择吗？

测试了具有肼键合配体[MoO ₂ L] _4的自组装四核钼（vi）配合物作为环辛烯和环己烯环氧化的（预）催化剂，无需添加额外的有机溶剂。特别注意了氧化剂在水中的TBHP与癸烷中的TBHP的比较。想法是测试整个过程的绿色。密度泛函理论计算用于支持和解释四核自组装系统的实验催化结果。
