Abstract The two layered double hydroxides ZnAl-LDH and MgAl-LDH were functionalized with bis(4-HOOC-phenyl)acenaphthenequinonediimine) (H(2)BIAN), leading to the intercalation of its dianion, which in a second step reacted with [Mo(CO)(3)X-2(NCMe)(2)] (X = I, Br), affording four new materials. These materials and the two complexes [Mo(CO)(3)X-2 (H(2)BIAN)(2)] (X = I, Br) were tested in the olefin epoxidation reaction with substrates cis-cyclooctene, styrene, 1-octene, trans-hex-3-en-1-ol, and R-(+)-limonene, using tert-butylhydroperoxide (tbhp) as oxidant. The new catalysts were particularly good for cis-cyclooctene and styrene (100\% conversions) and at least one heterogeneous catalyst was comparable to the homogeneous ones in the epoxidation of 1-octene and trans-hex-3-en-1-ol. The homogeneous catalysts were the best to oxidize R-(+ )-limonene (higher conversions).
