Anti-amyloidogenic activity of safranal towards induced HSA amyloids has been observed using a variety of techniques including fluorescence, UV–visible, CD, DLS and microscopies. The HSA solution was pre-incubated at 65 °C for 120 h and, in between, the growth of amyloid fibrils, using ThT agg...

Molecular interaction between BSA and safranal was seen in the present study using experimental and molecular docking methods, in addition, inhibitory effect of safranal towards BSA amyloid formation was also seen. UV–visible and fluorescence studies suggested the formation of 1:1 complex betwe...

The objective of this work was to study molecular binding of safranal to whey proteins by taking advantage of headspace solid-phase microextraction combined with gas chromatography (HS–SPME/GC), fluorescence and circular dichroism (CD) spectroscopies, and docking studies. The results of HS-SPME...

We developed a method to simultaneously and quantitatively measure four compounds commonly found in commercial cosmetics: 1,3-dimethylol-5,5-dimethylhydantoin (DMDMH) and its decomposition products 1-hydroxymethyl-5,5-dimethylhydantoin (1-MDMH), 3-hydroxymethyl-5,5-dimethylhydantoin (3-MDMH), an...

The reaction of alkyl trifluoro(organylsulfonylimino)propionates with phosphites occurs with NC transfer of the RSO2 group and leads to sulfonyl-substituted trifluoroalanine derivatives. The novel rearrangement is interpreted as cheletropic 1,4-cycloaddition of the phosphite and subsequent 1,2...

Cyclic voltammetry on [RhL4]+ (L = triisopropylphosphite) in 1,2-dimethoxyethane has shown that the complex undergoes a two-electron reduction to [RhL4]−, which is reoxidized to [RhL4]+ in two separate one-electron steps. The intermediate d9 species [RhL4] is a long-lived species to which a squa...

The first examples of the reactions of perfluoroalkanethiocarboxylic acid amides and trialkyl phosphites are presented. The reactions are shown to be dependent on the perfluoroalkyl chain length and the presence of proton-donating reagents. New fluorinated α-aminophosphonate derivatives are obt...

1-Alkynylphosphonates were obtained in good to high yields by simple heating of 1-alkynyl sulfones with trialkyl phosphites.

We have examined coordination of PR3 = triphenylphosphine, triethylphosphine, triisopropyl phosphite, trimethyl phosphite, and 1,3,5-triaza-7-phosphaadamantane (PTA) to the fragment RuII(bda) to better understand how different phosphine and phosphite ligands influence the electronic and structur...

Herein, we report the use of triisopropyl phosphite (TIP) as an effective substitute for triphenylphosphine in the Mitsunobu reaction of nucleoside analogs. In addition, the use of triphenyl phosphite as an alternative reagent for the expensive hexamethylphosphorous triamide (HMPT) in the Véliz...

The low molecular weight samples were examined to assign the nuclear magnetic resonance (NMR) signals, and to study the cyclic structure and the end group structure for poly[perfluoro(4-vinyloxyl-1-butene)]. While the penta-cyclic structure was dominant, the hexa-cyclic structure also existed. T...

Perfluoro-1,2-diethyl-1-phenylbenzocyclobutene under the action of SbF5 gives, after treatment of the reaction mixture with water, perfluoro-4-[1-(6-propyl-phenyl)-propylidene]cyclohexa-2,5-dienone along with the products of unusual pentafluorobenzene ring expansion – perfluorinated 4b,10-dieth...

Perfluoro-1-phenylindan (1) was obtained from perfluoroindan and pentafluorobenzene in the presence of SbF5. Compound 1 heated with antimony pentafluoride at 170°C and then treated with water gave a mixture of perfluorinated 9-methylfluorene (5), 9-hydroxy-9-methylfluorene (6), 9-methyl-1,2,3,4...

In the presence of antimony pentafluoride at 130 °C, the four-membered ring of perfluoro-1-(2-ethylphenyl)benzocyclobutene (2) undergoes cleavage, forming perfluoro-2-ethyl-2′-methyldiphenylmethane (5). Compound 5 is converted, under the action of SbF5 at 170 °C, to perfluoro-8,9-dimethyl-1,2...

The reaction of perfluoro-1,2-dichlorocyclobutene with t-butyllithium leads to replacement of Cl by Li. The lithio derivative was stable to −30°C and reaction with trimethylsilyl chloride gave perfluoro-1-chloro-2-trimethylsilylcyclobutene. The reaction of the latter with t-butyllithium leads t...

Perfluoro-1-phenyltetralin (1) heated with antimony pentafluoride at 130 °C, then treated with water, gave a mixture of perfluorinated 3-methyl-2-phenylindenone (3), 3-methyl-2-phenylindene (4), 3-hydroxy-1-methyl-3-phenylindan (5), 1-methyl-3-phenylindan (6), 9-methyl-1,2,3,4,5,6,7,8-octahydro...

Fluorinated ionomer p-perfluoro[1-(2-sulfonic)ethoxy]ethylated polyacrylonitrile-styrene (SFAS) (5) was synthesized via electron transfer reaction between polyacrylonitrile-styrene (AS) (1) and perfluoro-di[2-(2-fluorosulfonyl)ethoxy]propionyl peroxide (FAP) (2) and followed by alkali hydrolysis...
