Organometallic Oxides of Main Group and Transition Elements Downsizing Inorganic Solids to Small Molecular Fragments

CpMo(CO)3Cl as a precatalyst for the epoxidation of olefins

“…Measurements made after 69 h of reaction gave the same results as those obtained after 4 h, indicating that there was no significant conversion of CO into CO 2 . The reaction can therefore be written as shown in equation (1) in which the carbonyl groups are released unchanged and are not oxidised to CO 2 .…”

“…High oxidation state organometallic oxides have found numerous applications as catalysts for oxidation reactions [1]. Perhaps the most famous example, methyltrioxorhenium(VII) (MTO), is an efficient catalyst for olefin epoxidation (using H 2 O 2 as the oxidant), Baeyer Villiger oxidation, aromatic oxidation and metal carbonyl oxidation [2][3][4].…”

Self‐Assembly of Polyoxo Clusters and Extended Frameworks by Controlled Hydrolysis of Low‐Valent Uranium

“…[16,17] In particular, it is surprising that since the first report of a uranium cluster containing an isopolyoxometalate U 6 O 8 core in 1952 [18] only three additional examples of well-characterized uranium oxo clusters-all hexanuclear-have been described. [10][11][12] This contrasts dramatically with the extensive structural variety of transitionmetal polyoxometalate compounds [19][20][21] despite the similarity of the chemical properties of uranium with respect to Mo and W.…”

High oxidation state organomolybdenum and organotungsten chemistry in protic environments

“…These catalytic aspects have been recently reviewed and will not be covered here [33]. Other recent relevant reviews have appeared on organometallic oxides [34] and hydroxides [35] of the transition elements, as well as on dioxygen activation by organometallics of the early transition metals [36]. A concept article and a special report highlighting advances from our own group in aqueous Cp * Mo chemistry have also been published a few years ago [37,38].…”
