An efficient reaction between triphenylphosphine or triphenyl phosphite and 2-oxoindoline-3-ylidene derivatives in the presence of acetylenic esters leads to functionalized 2-oxoindoline-3-ylidene containing phosphorus ylieds or phosphonate esters. All compounds obtained in these reactions are stable and have good yields.

Article Synopsis
  • Organophosphorus flame retardants (OPFRs) are common in commercial products due to their effective flame-retardant properties, but they are also emerging pollutants with potential toxicity and environmental persistence.
  • This study developed a new detection method for 10 specific OPFRs in soil using matrix solid-phase dispersion extraction combined with gas chromatography-tandem mass spectrometry (GC-MS/MS).
  • The research focused on optimizing the extraction process by testing various sorbents and elution conditions, finding that using GCB as the sorbent and ethyl acetate as the solvent led to high extraction efficiency.

A mechanism of unusual tandem (MS/MS) fragmentation of protonated species of -(triphenyl-λ-phosphanylidene) derivatives, [M + H] to generate triphenylphosphine oxide (TPPO) within the mass spectrometer has been investigated and reported. Collision-induced dissociation of these molecules resulted in the generation of TPPO as a signature fragment. This fragment suggested the presence of a P-O bond in the structure which was contrary to the structure of the compound identified by nuclear magnetic resonance spectrometry (NMR) and single-crystal X-ray diffractometry (SXRD) techniques with a P═N bond rather than a P-O bond.

New 1,4-naphthoquinone derived by triphenylphosphaneylidene (PhP) and -substituted-hydrazine-1-carbothioamides were obtained during a one-pot reaction of 2,3-dichloro-1,4-naphthoquinone with thiosemicarbazides, PhP and in the presence of triethyl amine (EtN) as a catalyst. The structure of the ligands was established by ESI, IR, and NMR spectra, in addition to elemental analyses and X-ray structure analysis. On subjecting the newly prepared ligands with CuCl and PhP, autoxidation occurs, and ()-(2-(1,4-dioxo-3-(triphenyl phosphanylidene)-3,4-dihydronaphthalen-2(1)-ylidene)carbamothioyl)hydrazinyl)-((triphenylphosphanyl)oxy)copper derivatives were formed in very good yields.

This work reports on the reactive oxygen species (ROS) generation and the therapeutic activities of new triphenyl-phosphonium-labelled phthalocyanines (Pcs), the 2,9,16,23-tetrakis(N-(N-butyl-4-triphenyl-phosphonium)- pyridine-4-yloxy) Zn(II) Pc (3) and 2,9,16,23-tetrakis-(N-(N-butyl-4-triphenyl-phosphonium)-morpholino) Zn(II) Pc (4) upon exposure to light, ultrasound and the combination of light and ultrasound. Two types of ROS were detected: the singlet oxygen (O) and hydroxyl radicals. For light irradiations, only the O was detected.
