W niniejszej pracy zbadano wpływ mineralnych napełniaczy nieorganicznych, tj. dwóch rodzajów boehmitu (Catapal B i Pural SB) na wybrane właściwości miękkich kompozytów poli(chlorku winylu). Zbadano palność, twardość w skali Shore'a oraz przy rozciąganiu otrzymanych materiałów. Na podstawie uzyskanych wyników stwierdzono, że rodzaj ilość dodatku uniepalniającego znacząco wpływają kompozytów.
Polymeric aluminum organophosphates are a class of nanostructured aluminum-based compounds that can be considered organic and inorganic hybrid materials. Aluminum phosphates have attracted considerable interest due to their ability enhance composite materials’ mechanical characteristics, lightweight, thermal properties. Extensive studies shown the potential as component in development fire-retardant Aluminum–organophosphorus (APH) materials been prepared by reacting oxide hydroxide...
This paper presents the general synthesis of a comprehensive group P-chiral phosphinyl derivatives with natural coumarin-type motif. A chiral substituent was attached at third position coumarin molecule via Knoevenagel procedure using readily available phoshinylacetic acid esters without loss enantiomeric purity. The application salicylaldehyde-based allowed incorporation substituents different electron character into backbone these coumarins making them suitable for subsequent chemical...
In this paper flammability tests and detailed investigations of lignin-containing polymer composites’ properties are presented. Composites were obtained using bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA.GDA), ethylene glycol dimethacrylate (EGDMA), kraft lignin (lignin alkali, L) during UV curing. order to evaluate the influence modification addition flame retardant compounds on thermal resistance biocomposites, have been conducted. After with phosphoric acid (V) lignin, as...
Abstract Simple, efficient, clean, and stereospecific protocols of protection phosphorus atom with borane deprotection from the complexes tertiary phosphines in mild conditions are reported. The proposed protection/deprotection reactions tolerate a range functional groups lead to pure products excellent yield no need for application chromatographic or crystallisation purification procedures. For first time mechanisms phosphine have been studied based on experimental kinetic data as well...
A practical protocol for efficient synthesis of both PAMPO enantiomers as well related functionalised P-stereogenic phosphine oxides in 1–3 steps from effectively resolved (S P)-l-menthyl o-anisyl-(phenyl)phosphinylacetate has been developed. Examples non-stereoselective quaternisation a tertiary by alkyl halides have revealed.
The adducts of dirhodium tetraacylates and phosphines are characterized in solution by 1H 31P NMR spectroscopy at room temperature. A differentiation the enantiomers chiral phosphine ligands is easily performed signal integration after adduct formation with enantiopure Rh2[(R)-(+)-MTPA]4 complex (Rh*). Stereochemical aspects discussed terms discrimination diastereomerism. second type recognition was discovered, namely, that between two ligand molecules 2:1 across building block. Conditions...

Abstract A wide range of commercially available aldehydes have been applied to Knoevenagel condensation reaction give E-alkenylphosphine oxides and vinylphosphine oxides. The readily phosphinoylacetic acids derived from P(O)–H compounds were used as the starting materials in reaction, providing a highly stereoselective efficient method for constructing α,β-unsaturated phosphine Moreover, this simple practical procedure provides an alternative more environmentally friendly synthesis strategy...
This paper presents the efficient reduction of phosphinoylacetic acid esters and 3-phosphorylated coumarin to their corresponding phosphino-boranes using BH₃-THF complexes. Optimized conditions for resulted in high yields phosphinoborates. The straightforwardness efficiency process were demonstrated diarylphosphinoylacetic ethyl esters, as well P-stereogenic L-menthyl where simultaneous strong P=O bond ester group was exclusively observed first time. study also highlighted significant...
Colorectal cancer (CRC) is a global problem. Oncology currently practices conventional methods of treating this carcinoma, including surgery, chemotherapy, and radiotherapy. Unfortunately, their efficacy low; hence, the exploration new therapies critical. Recently, many efforts have focused on developing safe effective anticancer compounds. Some them include cannabinoids. In present study, we obtained cannabinoids, such as cannabidiol (CBD), abnormal cannabigerol (abn-CBG), cannabichromene...
