Uranium-mediated oxidative addition and reductive elimination.

Oxidative addition, and its reverse reaction reductive elimination, constitute two key reactions that underpin organometallic chemistry and catalysis. Although these reactions have been known for decades in main group and transition metal systems, they are exceptionally rare or unknown for the f-block. However, in recent years much progress has been made. In this Perspective article, advances i...

Direct Michael addition of alkenes via a cobalt-dinitrosyl mediated vinylic C-H functionalization reaction.

We report a one-pot, direct C-H functionalization reaction of alkenes mediated by [CpCo(NO)(2)]. All intermediates in the proposed reaction sequence have been characterized. A variety of Michael acceptors can be utilized with the one-pot procedure to give the desired cyclic tetra-alkyl-substituted, γ,δ-unsaturated compounds in good yields. We also provide a preliminary result for catalytic turn...

Ligand functionalization as a deactivation pathway in a fac-Ir(ppy)3-mediated radical addition.

Knowledge of the kinetic behavior of catalysts under synthetically relevant conditions is vital for the efficient use of compounds that mediate important transformations regardless of their composition or driving force. In particular, these data are of great importance to add perspective to the growing number of applications of photoactive transition metal complexes. Here we present kinetic, sy...

Functionalization of Polymer Nanoparticles by Thiol-Ene Addition

Syndiotactic 1,2 polybutadiene nanoparticles (volume average diameter 13 nm) were func tionalized in aqueous dispersion by free radical mercaptan addition. By appropriate choice of both water soluble radical initiator andmercaptan concentration, nanoparticles with a degree of functionalization of up to 85% were prepared using 3 mercaptopropionic acid methyl ester and 3 mercaptopropionic acid. O...

Selective Reduction of Dimedone

The selective hydrogenation of dimedone (1) to the corresponding monoketone 2 over palladium and Amberlyst 15 ® is reported. The product is a synthetic building block for the fragrance and pharmaceutical industry. Advantages of the new catalytic procedure are the high catalyst activity and selectivity, less by-product formation, avoidance of the presence of acid, and consequently, less salt for...
