We report a catalytic reductive alkylation reaction of primary or secondary amines with carboxylic acids. The two-phase process involves silane mediated direct amidation followed by catalytic reduction.

A small macrocycle comprising ether-bridged naphthyl units was prepared in a two-step synthesis. Single-crystal X-ray diffraction of two polymorphs are reported, one which showed multiple C−H⋅⋅⋅πnaphthyl interactions solvent molecule the cavity macrocycle. Chemical reduction led to C−O bond cleavages accompanied by Z/E isomerization. The resulting twofold negatively charged (E)-1,2-bis(2-naphth...

This paper describes the synthesis of a series of Pd(IV) complexes of general structure (N~C)(2)Pd(IV)(O(2)CR)(2) (N~C = a rigid cyclometalated ligand; O(2)CR = carboxylate) by reaction of (N~C)(2)Pd(II) with PhI(O(2)CR)(2). The majority of these complexes undergo clean C-O bond-forming reductive elimination, and the mechanism of this process has been investigated. A variety of experiments, inc...

Microbial communities inhabiting the deep-sea salt-saturated anoxic lakes of the Eastern Mediterranean operate under harsh physical-chemical conditions that are incompatible with the lifestyle of common marine microorganisms. Here, we investigated a stable three-component microbial consortium obtained from the brine of the recently discovered deep-sea salt-saturated Lake Thetis. The trophic net...

Abstract Nickel-catalyzed reductive homocoupling of aryl ethers has been achieved with Mg(anthracene)(thf)3 as a readily available low-cost reductant. DFT calculations provided rationale for the specific efficiency diorganomagnesium-type two-electron reducing agent. The show that dianionic anthracene-9,10-diyl ligand reduces two ether substrates, resulting in reaction through supply electrons t...

The cleavage of silicon–hydrogen bonds to generate silicon-containing metal complexes has played an essential role in the preparation organosilicon compounds. Herein, we report reaction cyclopentadienone iridium complex 1 with hydrosilanes afford hydroxycyclopentadienyl silyl 4 via umpolung Si–H bond. nucleophilicity Ir–Si bond resulting was demonstrated allyl halide and ethyl acrylate. Further...

The synthetic potential of stereoselective, palladium-catalyzed hydro(het)arylation reactions of bi-, tri- and tetracyclic (hetero)alkenes in the presence of phospines and arsines as highly efficient ligands was studied. The mechanism of this reductive Heck reaction becomes more complex in the case of benzonorbornenes. Hydroarylation of diazabicyclo-[2.2.1]heptenes provides a stereoselective ac...
