In the presence of a catalytic amount of chiral phosphoric acid, nucleophilic addition of N-monosubstituted hydrazones to N-Boc imines affords differentially protected vicinal diamines in the form of b-amino N,N’-dialkyldiazenes in excellent yields with hi ...
The palladium-catalyzed reaction of a-haloketones with isocyanides afforded -oxo-ketenimines through alpha-hydride elimination of the beta-oxo-imidoyl palladium intermediates. Reaction of these relatively stable alpha-oxo ketenimines with nucleophiles suc ...
The kinetics for the reactions of hypoiodous acid (HOI) with various phenols (phenol, 4-nitrophenol, 4-hydroxybenzoic acid), 3-oxopentanedioic acid (3-OPA) and flavone were investigated in the pH range of 6.0-11.0. The apparent second order rate constants ...
Catalysis fulfills the promise that high-yielding chemical transformations will require little energy and produce no toxic waste. This message is carried by the study of the evolution of molecular catalysis of some of the most important reactions in organi ...

Background: Intrigued by the fact that aminoadamantane derivatives, bearing the active 1,2-ethylenediamine moiety, are promising antitubercular agents, we report herein the synthesis and the antitubercular evaluation of N,N'-substituded-4,4'-[adamantane-2, ...

Herein, we report the synthesis and characterisation of the first terminal uranium(V) sulfide and a related UV trithiocarbonate complex supported by sterically demanding tris(tert-butoxy)siloxide ligands. The reaction of the potassium-bound UV imido comple ...

During chlorination of bromide-containing waters, a significant formation of brominated disinfection byproducts is expected. This is of concern because Br-DBPs are generally more toxic than their chlorinated analogues. In this study, synthetic water sample ...

Thermolysis of the nitride-bridged diuranium(IV) complex Cs{(-N)U(OSi((OBu)-Bu-t)(3))(3)} (1) showed that the bridging nitride behaves as a strong nucleophile, promoting N-C bond formation by siloxide ligand fragmentation to yield an imido-bridged sil ...

Homing endonucleases, such as I-DmoI, specifically recognize and cleave long DNA target sequences (∼20 bp) and are potentially powerful tools for genome manipulation. However, inefficient and off-target DNA cleavage seriously limits specific editing in com ...

Thiol-ene addition of thioacetic acid A is widely used in the synthesis of thiols from vinyl precursors, but so far has not been conducted on non-conjugated vinyl nitriles. The challenge when vinyl nitriles are used is to selectively conduct the thiol-ene ...
