We reported the new synthesis of Sm2Co17 particles by a microwave-assisted combustion (MACS) method. This process enables the controlled decomposition of Sm(NO3)3 and Co(NO3)2 into SmCo-O particles, followed by calcium reduction-diffusion. This SmCo-O particle provides an approach for achieving high magnetic properties in Sm2Co17 magnetic materials. The rhombohedral Sm2Co17 particles can be incorporated into epoxy resin and oriented, displaying a square-like hysteresis loop. The particles display magnetic properties at room temperature, with a saturation magnetization of 112.3 emu/g, coercivity of 5.6 kOe, and a maximum energy product of 9.4 MGOe. This method improves the synthesis efficiency of rare earth cobalt-based nano-materials, expands the synthesis scope, and provides ideas for the synthesis and applications of other rare earth nano-materials.

The photoredox-catalyzed decarboxylative cross-coupling reaction of aryl acetic acids and aryl nitriles has been achieved under an argon atmosphere in high yields. This method provides a fast way to obtain prevalent aryl acetic acids from an abundant natural source. A tentative radical mechanism has been proposed. [ABSTRACT FROM AUTHOR]

The PhI(OAc) 2 -promoted 1,2-transfer reaction between allylic alcohols and thiophenols, conducted in an argon atmosphere, has proven to be effective in producing β-carbonyl sulfides from 1,1-disubstituted allylic alcohols in high yields. This method offers a fast and efficient way to synthesize β-carbonyl sulfides, which are valuable intermediates in organic synthesis. This discussion focuses on the effects of the oxidizer, temperature, and solvent on the reaction. A proposed tentative mechanism for this reaction is also discussed.

The title compound, C 17 H 13 FN 2 , was synthesized as a potential ligand for the construction of metal-organic frameworks. The two indole motifs present two potential coordination modes. It crystallizes in the ortho-rhom-bic system with space group P 2 1 2 1 2 1 . The dihedral angle between the fused ring systems is 68.77 (10)°. Weak F⋯H inter-actions are observed in the crystal., (© Guozhe Guo 2023.)
