Synthesis of new hybrid 1,4-thiazinyl-1,2,3-dithiazolyl radicals via Smiles rearrangement

2017

The condensation reaction of 2-aminobenzenethiols and 3-aminopyrazinethiols with 2-amino-6-fluoro-N-methylpyridinium triflate afforded thioether derivatives that were found to undergo Smiles rearrangement and cyclocondensation with sulphur monochloride to yield new hybrid 1,4-thiazine-1,2,3-dithiazolylium cations. The synthesized cations were readily reduced to the corresponding stable neutral radicals with spin densities delocalized over both 1,4-thiazinyl and 1,2,3-dithiazolyl moieties. peerReviewed

Fluorinated heterocyclic compounds: an assay on the photochemistry of some fluorinated 1-oxa-2-azoles: an expedient route to fluorinated heterocycles

2004

Abstract Photoinduced heterocyclic rearrangements of ON bond-containing azoles have been claimed in the synthesis of target fluorinated heterocyclic compounds. In this context, the photochemical behavior of some fluorinated 1,2,4-oxadiazoles has been investigated. Irradiations of 3-amino-5-perfluoroalkyl-1,2,4-oxadiazoles at λ =313 nm in methanol gave open-chain products arising from a reaction of the nucleophilic solvent with either the first formed ring-photolytic species or with a nitrilimine moiety generated from it. Differently, irradiations in methanol with the presence of triethylamine (TEA) followed competing phototransposition pathways leading to the ring-isomers 2-amino-5-perfluo…

Stabilise, balance and adjust : Framing the early years transitions of children whose parents work non‐standard hours

2022

This study examined talk by parents about the early years transitions of their children (n = 7) in the context of parental non-standard working hours and Finnish early childhood education and care (ECEC) services. Parents were interviewed at three time points: when their child was aged one, four, five or six years (a total of 21 interviews). The third interview was conducted during the COVID-19 pandemic. This article focuses on the children's ECEC transitions and the interpretative frames used by parents when talking about their work and childcare. The frames used by the parents to discuss the children's transitions were stabilising the children's lives, balancing between staying at home an…

Układ częściowy obejmujący wierzytelności zabezpieczone rzeczowo a zawieszenie egzekucji z mocy prawa

2018

Niniejsze opracowanie odnosi się do problematyki wpływu otwarcia przyspieszonego postępowania układowego z układem częściowym na postępowanie egzekucyjne dotyczące wierzytelności zabezpieczonej rzeczowo na składnikach majątku dłużnika. Zaprezentowany zostanie pogląd prawny, i jego uzasadnienie, według którego, w przypadku gdy wierzytelność zabezpieczona rzeczowo na majątku dłużnika zostaje objęta układem częściowym wówczas egzekucja co do niej ulega bezwzględnemu zawieszeniu z mocy samego prawa (ipso iure)
