In response to the escalating global energy requests and need address them in a sustainable manner, researchers have identified hydrogen as an vector that provides practical way store use from renewable sources. To make step forward, electrocatalytic properties for evolution reaction alkaline medium of graphite electrodes modified with combinations nickel phosphite free-base porphyrins were inv...

Electroless nickel plating baths have to be discarded when levels of phosphites build up and interfere with the plating process. OWMC funded research conducted at ORTECH International to determine whether phosphites could be removed from plating bath solution. The first attempt to do this by adsorption on flyash was unsuccessful. However, the use of calcium ion to precipitate calcium phosphite ...

A metal-free stereoselective reductive coupling reaction between isatins and aldehydes is reported. The reaction relies on commercial diethyl phosphite (∼€70 kg-1) as the stoichiometric reductant. Base-catalyzed Pudovik addition and phosphonate/phosphate rearrangement achieved polarity inversion on the isatin, and the derived carbanions were trapped by aldehydes with subsequent dialkoxyphosphin...

The title compound, C(12)H(9)Cl(2)NO(2), was prepared by the esterification of 3,7-dichloro-quinoline-8-carboxylic acid with triethyl phosphite. The crystal structure is stabilized by aromatic π-π stacking between the benzene and the pyridine rings of neighbouring mol-ecules [centroid-centroid distances = 3.716 (2) and 3.642 (2) Å]. In addition, weak inter-molecular C-H⋯N hydrogen bonds are pre...

A protected 2-aminopurine nucleoside suitable for incorporation into oligodeoxynucleotides using phosphite triester chemical synthesis procedures has been prepared via oxidation of a purine hydrazino derivative with silver (I) oxide. Five oligodeoxynucleotides containing Eco RI and Bam HI recognition sites have been prepared such that, in the double stranded form, the 2-aminopurine base has eit...

The new 7r-donor bis-(phenylenedithio)-tetrathiafulvalene (5), synthesized via phosphite coupling o f 2-oxo-l,3-dithiolo-[4,5b][l,4]-benzodithiin (4), has been prepared in 5 steps start­ ing from 1,2-dimercaptobenzene and chloroacetyl chloride. Spectroscopic and electrochemical data point to a close similarity o f 5 and dibenzo-tetrathiafulvalene (DB-TTF). 5 forms a highly conducting radical-ca...

The stereoselective synthesis of diethyl (S)or (R)-IX-[( O-pivaloylhexapyranosyl)amino]benzylphosphonates is achieved via Lewis acid catalyzed addition of diethyl phosphite to O-pivaloylated Nbenzylidene-{3-D-galactosylamine or N-benzylidene-IX-D-arabinopyranosylamine. The process can also be performed by a one-pot procedure selectively giving (S)-aminophosphonic acid derivatives from galactosy...

In the title triangulo-triruthenium compound, [Ru(3)(C(6)H(12)Cl(3)O(3)P)(CO)(11)], one equatorial carbonyl ligand is substituted by a monodentate phosphite ligand, leaving one equatorial and two axial carbonyl ligands on one Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. In the crystal structure, the mol-ecules are linked into a one-dimen...
