Selective Air Oxidation of Bis- and Trisphosphines Adsorbed on Activated Carbon Surfaces [PDF]

open access: yesMolecules
Bis- and trisphosphines incorporating methylene and aryl spacers readily adsorb on the surface of porous activated carbon (AC). The adsorption can be performed in the absence of solvents, even when the phosphines have high melting points, or from ...

Catalytic ammonia formation from dinitrogen, water, and visible light energy [PDF]

open access: yesNature Communications
The development of the production method for green ammonia, which is produced only from ubiquitous and clean small molecules (i.e., dinitrogen and water) using renewable energy, has been desired for a next-generation carbon-free energy carrier to build a

Synthesis of Mixed Arylalkyl Tertiary Phosphines via the Grignard Approach

open access: yesMolecules, 2022
Trialkyl and triaryl phosphines are important classes of ligands in the field of catalysis and materials research. The wide usability of these low-valent phosphines has led to the design and development of new synthesis routes for a variety of phosphines.

The Usefulness of Trivalent Phosphorus for the Synthesis of Dendrimers

open access: yesMolecules, 2021
Dendrimers are hyperbranched macromolecules, which are synthesized step-by-step by the repetition of a series of reactions. While many different types of dendrimers are known, this review focusses on the use of trivalent phosphorus derivatives ...

Phosphine Organocatalysis [PDF]

open access: yesChemical Reviews, 2018
The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a phosphine to an electrophilic starting material, producing a reactive zwitterionic intermediate, generally under mild conditions. In this Review, we classify nucleophilic phosphine catalysis reactions in terms of their electrophilic components. In the majority of

Phosphine‐Stabilized Pnictinidenes [PDF]

open access: yesChemistry – A European Journal, 2021
AbstractThe reaction of the intramolecular germylene‐phosphine Lewis pair (o‐PPh2)C6H4GeAr* (1) with Group 15 element trichlorides ECl3 (E=P, As, Sb) was investigated. After oxidative addition, the resulting compounds (o‐PPh2)C6H4(Ar*)Ge(Cl)ECl2 (2: E=P, 3: E=As, 4: E=Sb) were reduced by using sodium metal or LiHBEt3.
