We report a ligand-controlled nickel-catalyzed reductive hydroarylation of styrenes with predictable and controllable regioselectivity. With a diamine ligand, the reaction produces selective linear hydroarylation products. Alternatively, with a chiral PyrOx ligand, branch-selective enantioenriched 1,1-diarylalkane products are obtained. Preliminary mechanistic results are consistent with a reductive Heck process.

A highly selective hydrogenation of alkynes using an air-stable and readily available manganese catalyst has been achieved. The reaction proceeds under mild reaction conditions and tolerates various functional groups, resulting in (Z)-alkenes and allylic alcohols in high yields. Mechanistic experiments suggest that the reaction proceeds via a bifunctional activation involving metal-ligand cooperativity.
Nickel-catalyzed anti-Markovnikov hydroarylation of alkenes

We have developed a nickel-catalyzed hydroarylation of alkenes using aryl halides as coupling partners. Excellent anti-Markovnikov selectivity is achieved with aryl-substituted alkenes and enol ethers. We also show that hydroarylation occurs with alkyl substituted alkenes to yield linear products. Preliminary examination of the reaction mechanism suggests irreversible hydrometallation as the selectivity determining step of the hydroarylation.
One-Pot Electrochemical Nickel-Catalyzed Decarboxylative Sp2-Sp3 Cross-Coupling

A one-pot electrochemical nickel-catalyzed decarboxylative sp2-sp3 cross-coupling reaction has been developed using redox-active esters prepared in situ from alkyl carboxylates and N-hydroxyphthalimide tetramethyluronium hexafluorophosphate (PITU). This undivided cell one-pot method enables C-C bond formation using inexpensive, benchtop-stable reagents with isolated yields up to 95% with good functional group tolerance, which includes nitrile, ketone, ester, alkene and selectivity over other aromatic halogens.

A series of dipeptides were designed as potential agonists of the human KiSS1-derived peptide receptor (hGPR54). While the sequence Arg-Trp-NH2was the most efficient in terms of affinity, we established a convergent synthetic strategy to optimi
Iron-catalyzed olefin hydrogenation at 1 bar H2 with a FeCl3-LiAlH4 catalyst

The scope and mechanism of a practical protocol for the iron-catalyzed hydrogenation of alkenes and alkynes at 1 bar H2 pressure were studied. The catalyst is formed from cheap chemicals (5 mol% FeCl3-LiAlH4, THF). A homogeneous mechanism operates at early stages of the reaction while active nanoparticles form upon ageing of the catalyst solution. This journal is
Iron/tetramethylethylenediamine-catalyzed ambient-temperature coupling of alkyl grignard reagents and aryl chlorides
Rushworth, Philip J.,Hulcoop, David G.,Fox, David J.
, p. 9517 - 9521 (2013/10/08)
Tetramethylethylenediamine (TMEDA) acts as cheap and readily removed ligand in the iron-catalyzed coupling of alkyl Grignard reagents and activated aryl chlorides. The use of TMEDA allows for low ligand and iron catalyst loading as well as an increased reaction concentration and an ambient reaction temperature on a mole scale.
Aryl-aryl interactions as directing motifs in the stereodivergent iron-catalyzed hydrosilylation of internal alkynes
Belger, Christian,Plietker, Bernd
, p. 5419 - 5421 (2012/07/03)
The defined Fe hydride complex FeH(CO)(NO)(Ph3P)2 is highly active as a catalyst for selective hydrosilylation of internal alkynes to vinylsilanes. Depending on the silane employed either E- or Z-selective hydrosilylation products were formed in excellent yields and good to excellent stereoselectivities.
Alpha-helical mimetics

Page/Page column 92, (2011/05/18)
Benzoyl urea derivatives that are alpha helical peptides mimetics that mimic BH3-only proteins, compositions containing them, their conjugation to cell-targeting-moieties, and their use in the regulation of cell death are disclosed. The benzoyl urea derivatives are capable of binding to and neutralizing pro-survival Bcl-2 proteins. Use of benzoyl urea derivatives in the treatment and/or prophylaxis of diseases or conditions associated with deregulation of cell death are also described.
