Quintavalla, Arianna;Veronesi, Ruben;Speziali, Laura;Martinelli, Ada;Zaccheroni, Nelsi;Mummolo, Liviana;Lombardo, Marco research published 《 Allenamides Playing Domino: A Redox-Neutral Photocatalytic Synthesis of Functionalized 2-Aminofurans》, the research content is summarized as follows. A photoredox catalytic synthesis of functionalized 2-aminofurans I [R = OPh, 2-oxooxazolidin-3-yl, indol-1-yl, etc.; R¹ = Me, Ph, 2-thienyl, etc.; R² = H, Me, CO₂Et, etc.] was proposed starting from α-halo carbonyl substrates and N-allenamides. The use of visible light as green energy source, redox-neutral nature of the transformation allowing to avoid additives and strong oxidants, mild reaction conditions and the functional groups tolerance, low photocatalyst loading and the absence of excess reagents, one-pot formation of three new bonds in a domino sequence, these features of this protocol made it particularly efficient and sustainable. According to mechanistic hypothesis, the transformation was configured as a double radical-polar crossover reaction, in which the photocatalyst was excited, oxidized and reduced twice for each mol. of 2-aminofuran produced. The novelty of the designed synthetic approach also lied in the use of N-allenamides as substrates, which, after the addition of the first electrophilic radical, preserve a further reactive π-system, made possible the addition of a second α-keto radical and enabling the installation of a keto functionality at a remote position. The good yields, broad scope and possibility to further synthetically elaborate the obtained furans made this protocol particularly promising for the construction of useful products.

V. research published 《 Low-melting phthalonitrile monomers containing maleimide group: Synthesis, dual-curing behavior, thermal and mechanical properties》, the research content is summarized as follows. Novel dual-functional phthalonitrile monomers containing a maleimide group were synthesized and characterized. Ortho, meta, and para isomers were obtained and only the meta-isomer can be considered as a low melting phthalonitrile monomer with a m.p. of 107.4°C. Anal. of the dual-curing behavior of monomers showed radical homopolymerization of maleimides followed by phthalonitrile polymerization with the formation of isoindoline, triazine, and phthalocyanine ring structures. Two alternative copolymerization processes of maleimide groups via ene reaction and ring-opening amidation were investigated. The approach of dual-curing maleimide and phthalonitrile fragments in a single mol. allowed combining the excellent inherent mech. properties of bismaleimide resins and the outstanding thermo-oxidative stability of phthalonitriles. After curing of both functional groups impact strength was as high as 11.81 kJ m^-2, flexural strength was 108 MPa, Young’s modulus was 4.38 GPa. On the contrary, T_g of this polymeric system was above 370°C and T_5% was higher than 450°C in air.

ZnTSBPc pigment is anchored to magnetite ore particle (Fe₃O₄) and this composite is immobilized on glassy C electrode (GCE) and used for the electrochem. sensing of thiocyanate (SCN^–) using cyclic voltammetry (CV). The GCE/ZnTSBPc and GCE/ZnTSBPc- Fe₃O₄ displayed linear response in the dynamic quant. range 0.150 to 3.400 μM and 0.090 to 8.640 μM with sensitivity values 383.918 and 618.670 μA μM^-1 cm^-2, resp. Also, GCE/ZnTSBPc and GCE/ZnTSBPc-Fe₃O₄ electrodes were employed for designing a chronoamperometric sensor for thiocyanate in the quant. range 0.050-0.450 μM, with sensitivity values 166.350 and 3852.687 μA μM^-1 cm^-2, resp. Results inferred that ZnTSBPc-Fe₃O₄ composite exhibited higher catalytic performance compared to ZnTSBPc administered GCE. The enhanced activity is ascribed to the increase in conductivity with an enhanced surface area of the composite. Also, the fabricated sensor exhibited good stability and superior selectivity for the thiocyanate in presence of coexisting mols.

The authors introduce phosphorescent Pt aryl acetylide complexes supported by tert-butyl-isocyanide and strongly σ-donating acyclic diaminocarbene (ADC) ligands. The precursor complexes cis-[Pt(CNtBu)₂(CCAr)₂] (4a–4f) are treated with diethylamine, which undergoes nucleophilic addition with one of the isocyanides to form the cis-[Pt(CNtBu)(ADC)(CCAr)₂] complexes (5a–5f). The new compounds incorporate either electron-donating groups (4-OMe and 4-NMe₂) or electron-withdrawing groups [3,5-(OMe)₂, 3,5-(CF₃)₂, 4-CN, and 4-NO₂] on the aryl acetylide. Exptl. HOMO-LUMO gaps, estimated from cyclic voltammetry, span the range of 2.68-3.61 eV and are in most cases smaller than the unsubstituted parent complex, as corroborated by DFT. In the ADC complexes, peak photoluminescence wavelengths span the range of 428 nm (2a, unsubstituted phenylacetylide) to 525 nm (5f, 4-NO₂-substituted), with the substituents inducing a red shift in all cases. The phosphorescence E_0,0 values and electrochem. HOMO-LUMO gaps are loosely correlated, showing that both can be reduced by either electron-donating or electron-withdrawing substituents on the aryl acetylides. The photoluminescence quantum yields in the ADC complexes are 0.044-0.31 and the lifetimes are 4.8-14μs, a factor of 1.8-10x higher (for Φ_PL) and 1.2-3.6x longer (for τ) than the resp. isocyanide precursor (Φ_PL = 0.014-0.12, τ = 2.8-8.2μs).
