   Abstract The synthesis and reactivity of 3,8‐dibromo‐dodecafluoro‐benzo‐fused BOPHY2are reported, via S_NAr with O‐, N‐ S‐ and C‐nucleophiles, and in Pd(0)‐catalyzed cross‐coupling reactions (Suzuki and Stille). The resulting perfluoro‐BOPHY derivatives were investigated for their reactivity in the presence of various nucleophiles. BOPHY3displays reversible color change and fluorescence quenching in the presence of bases (Et₃N, DBU), whereas BOPHY7reacts preferentially at the α‐pyrrolic positions, and BOPHY8undergoes regioselective fluorine substitution in the presence of thiols. The structural and electronic features of the fluorinated BOPHYs were studied by TD‐DFT computations. In addition, their spectroscopic and cellular properties were investigated; BOPHY10shows the most red‐shifted absorption/emission (λ_max659/699 nm) and7the highest fluorescence (Φ_f=0.95), while all compounds studied showed low cytotoxicity toward human HEp2 cells and were efficiently internalized.

4. Interaction between perfluoro‐octanoic sulfonate and common antibiotics induces developmental anomalies and lethality in Xenopus laevis

   Abstract BackgroundPerfluoroalkyl substances (PFAS) are persistent environmental contaminants previously used for industrial purposes as a non‐stick coating and flame retardant. The stability of these molecules prevents their breakdown, which results in ground water contamination across the globe. Perfluoroalkyl substances molecules are known to bioaccumulate in various organisms. However, the health consequences remain unclear due to the large number of molecules in the PFAS family and different effects on various tissues. Here, we use the frogXenopus laevisto investigate the developmental consequences of exposure to the PFAS molecule perfluoro‐octanoic sulfonate (PFOS). ResultsWe find that exposure to high levels of PFOS results in significant axial shortening of developing tadpoles. Further, we find that PFOS exposure results in a dose‐dependent formation of a cellular mass in the dorsal fin. Unexpectedly, we found that these developmental phenotypes are exacerbated upon co‐exposure with commonly used antibiotics. Specifically, PFOS and gentamicin co‐treatment results in increased apoptosis, loss of cellular integrity, and increased overall lethality. ConclusionsOur results suggest a mechanism whereby gentamicin reaches levels that are toxic to mitochondria only in the presence of PFOS. These findings add to our understanding of PFOS exposure to vertebrate development and present an added concern with potential interactions with antibiotics.

5. Dual oxidase/oxygenase reactivity and resonance Raman spectra of {Cu ₃ O ₂ } moiety with perfluoro- t -butoxide ligands

   Brazeau, Sarah E.; Norwine, Emily E.; Hannigan, Steven F.; Orth, Nicole; Ivanović-Burmazović, Ivana; Rukser, Dieter; Biebl, Florian; Grimm-Lebsanft, Benjamin; Praedel, Gregor; Teubner, Melissa; et al (May 2019, Dalton Transactions)

   A Cu( i ) fully fluorinated O-donor monodentate alkoxide complex, K[Cu(OC 4 F 9 ) 2 ], was previously shown to form a trinuclear copper–dioxygen species with a {Cu 3 (μ 3 -O) 2 } core, T OC4F9 , upon reactivity with O 2 at low temperature. Herein is reported a significantly expanded kinetic and mechanistic study of T OC4F9 formation using stopped-flow spectroscopy. The T OC4F9 complex performs catalytic oxidase conversion of hydroquinone (H 2 Q) to benzoquinone (Q). T OC4F9 also demonstrated hydroxylation of 2,4-di- tert -butylphenolate (DBP) to catecholate, making T OC4F9 the first trinuclear species to perform tyrosinase (both monooxygenase and oxidase) chemistry. Resonance Raman spectra were also obtained for T OC4F9 , to our knowledge, the first such spectra for any T species. The mechanism and substrate reactivity of T OC4F9 are compared to those of its bidentate counterpart, T pinF , formed from K[Cu(pin F )(PR 3 )]. The monodentate derivative has both faster initial formation and more diverse substrate reactivity.
