Schirmer, Marie-Luis published the artcileOrganocatalyzed Reduction of Tertiary Phosphine Oxides, Category: catalysis-chemistry, the publication is Advanced Synthesis & Catalysis (2016), 358(1), 26-29, database is CAplus.

A novel selective catalytic reduction method of tertiary phosphine oxides to the corresponding phosphines has been developed. Notably, the reaction proceeds smoothly with low catalyst loadings of 1-5 mol% even at low temperature (70¡ã). Under the optimized conditions various phosphine oxides could be selectively reduced and the desired phosphines were usually obtained in excellent yields above 90%. Furthermore, authors have developed a one-pot reaction sequence for the preparation of valuable phosphine¡¤borane adducts. Simple addition of BH₃¡¤THF subsequent to the reduction step gave the desired adducts in yields up to 99%.

A stereoselective synthetic method is reported for the mol. framework found in common daucane and isodaucane sesquiterpenoid natural products. The synthetic method constitutes a scalable, modular, and also asym. access to a complex natural product scaffold, wherein the substitution pattern and the stereochem. can be adjusted simply by choosing different starting materials. The method allows the rapid introduction of diverse heterocyclic substructures such as (benzo)furans, (benzo)thiophenes, dithiins, thiazoles, and indoles, which actually also facilitate and direct the key intramol. annulation step.

A new one-pot synthesis of allyldiphenylphosphine oxide (I) has been developed using a tandem S_n2′-Michaelis-Arbuzov sequence. The application of microwave heating lowers the reaction time significantly. Thus, reaction of Ph₂POEt with CH₂:CHCH₂Br in a sealed ampul with microwave irradiation for 2 min affords I in 86% yield. Conventional heating of the reactants for 1 h at 130¡ã afford I in 85% yield.

Gaspar, Rafael D. L. published the artcileLuminescent oxygen probes based on Tb^III complexes chemically bonded to polydimethylsiloxane, Safety of Allyldiphenylphosphine oxide, the publication is Sensors and Actuators, B: Chemical (2019), 557-568, database is CAplus.

In this work, the functionalization degree of siloxane crosslinkers by allyldiphenylphosphine oxide (adppo) and its effect on the performance of a lanthanide-based optical oxygen sensor were evaluated. Linear poly(dimethyl-co-hydromethylsiloxane) (PMS) and cyclic tetramethylcyclotetrasiloxane (D4i) crosslinkers were functionalized with different concentrations of adppo to chem. bond the [Tb(dcba)₃]¡¤1/2H₂O (dcba = dichlorobenzoate) complex. Mech. stable luminescent silicone membranes were obtained after the curing of the poly(dimethylsiloxane)-vinyl terminated siloxane backbone with the pre-functionalized crosslinkers. Sensing materials exhibit green emission upon 350 nm excitation, and their luminescent properties are dependent of functionalization degree of the crosslinkers. The luminescent sensor materials show fully reversible response and non-linear Stern-Volmer plots, which are fitted by two quenching parameter model, with highest KSV of 0.08930%^-1 when using functionalized D4i as crosslinker and complex concentration of 0.75%.

An efficient synthesis of the C(3)-C(12) aldehyde fragment of 24-demethylbafilomycin C₁ was accomplished for assembling the 16-membered plecomacrolide skeleton according to a 1,3-diene-ene ring-closing metathesis (RCM) strategy. A boron-mediated anti-selective aldol condensation of Abiko’s chiral propionate was used to secure the C(6) and C(7) stereogenic centers while the C(8) chirality was introduced from a chiral building block. The dithiane alkylation and the Me ketone Horner-Wittig olefination using allyldiphenylphosphine oxide were employed for construction of the requisite (E)-1,3-diene subunit.

2-Hydroxy-6-phosphinyl-5-hexenyl tosylates, oxirane ring-opening products derived from glycidyl tosylates and phosphinyl- substituted allyl anions, undergo domino S_N2-Michael reactions with primary amines to give 6-phosphinylmethyl piperidin-3-ols.
