Transition metal-catalyzed addition of arylboronic acids to 2-formylbenzoates afforded 3-substituted phthalides. By using SPINOL-based phosphites as ligands, a Rh(I)-catalyzed asymmetric version of such an addition reaction was achieved.

From literature data on partition coefficients and in some cases solubilities in nonaqueous solvents we have been able to determine Abraham descriptors for several series of organophosphorus compounds including the dialkyl- and diaryl-phosphates (dialkylphosphoric acids), trialkyl- and triphenyl-phosphates, dialkylphosphinic acids and diphenylphosphinic acid, trialkyl- and triaryl-phosphine oxi...

The use of phosphites in second generation, ruthenium-based olefin metathesis pre-catalysts leads to an improvement in catalyst stability and activity at low catalyst loadings.

A series of structurally related antiviral antibiotics, fluvirucins A1, A2, B1, B2, B3, B4 and B5 have been isolated from the fermentation broths of five unidentified actinomycete isolates. Based on spectroscopic analysis, partial degradation experiments and 13C-enriched acetic acid-fed biosynthetic studies, their structures were elucidated to be 2.6,10-trialkyl-3(or 9)-aminoglycosyl-13-trideca...

We here demonstrate a new route for deposition of phosphorous based materials by atomic layer (ALD) using the phosphites Me3PO3 or Et3PO3 as precursors. These contain in oxidation state (III) and are open reduced phases ALD. have investigated their applicability synthesis LiPO AlPO characterized growth means situ quartz crystal microbalance.

An ionophore-doped sensing membrane phosphate (PO4) microsensor based on bis(dibromophenylstannyl)methane (Bis microsensor) is described. The Bis microsensor showed a Nernstian response. The response of the Bis microsensor was log-linear down to a monohydrogen phosphate ion (HPO42-) concentration of 0.5 μM (corresponding to 1.0 μM of orthophosphate at pH 7.2), whereas the detection limit of PO4...

The reaction of triarylantimony diacetates [Ar3Sb(OAc)2] with dialkyl H-phosphites [H-PO(OR)2] in the presence of a Pd(PPh3)4 (5 mol%) catalyst led to the formation of arylphosphonates in moderate to excellent yield under base-free conditions. This reaction is the first example of carbon-phosphorus bond formation by using an organoantimony compound as a pseudo-halide.

A recently introduced empirical nucleophilicity index for a series of nand p-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. The model is validated against kinetic data of alkenes, phosphanes, phosphites and amines interacting with the corresponding electrophilic partner. The predictive character of t...

Phosphites are industrially important ligands for the Rh-catalysed hydroformylation of olefins because they produce more active catalysts than phosphines, which is mainly due to their strong π-acceptor properties facilitating CO dissociation from metal centre. Herein, effect three prominent phosphite (triphenylphosphite, Alkanox and BiPhePhos) on catalyst speciation during turnover investigated...
