“…51 Additionally, the activation energy for the first process is similar to the sublimation enthalpy of terephthalic acid (98.115 kJ/mol). 53 As the reactions were performed around the sublimation temperature (>290 °C), 54,55 it seems likely that the first region is limited by the sublimation of terephthalic acid. Gas phase terephthalic acid is then able to react with the surface of the precursor particles.…”

Acetic acid, an alternative green solvent, was utilized for the solvothermal synthesis of four 2D materials of composition [Zr2O2(OAc)2(BDC-F)], [Zr2O2(OAc)2(BDC-F4)], [Zr2O2(OAc)2(BDC)], and [Zr2O2(OAc)2(NDC)] (BDC, terephthalate; BDC-F, 2-fluoroterephthalate; BDC-F4, tetrafluoroterephthalate; NDC, 2,6-naphthalenedicarboxylate). The first three compounds were subsequently reacted with terephthalic acid in solid-state reactions to form porous MIL-140A-type metal–organic frameworks and mixed-linker derivatives ([ZrO(BDC)1–x (BDC-Y) x ], x = 0–0.18, Y = F, F4). The reaction kinetics of the formation of MIL-140A were investigated with the aid of time-resolved synchrotron and temperature-resolved in-house X-ray powder diffraction experiments. Thorough compositional analyses and solid-state NMR spectroscopic experiments were used to assess the crystallographic ordering of the different linker molecules. Additionally, acetic acid-based routes for the direct synthesis of MIL-140A-NO2 and a novel MIL-140A-(CH3)2 derivative were discovered.

“…Compound 7 was prepared by reductive methylation 38 of 4-cyclopropylaniline. 39 Kugelrohr distillation afforded a colorless oil which was characterized for identity and purity (>98%) by NMR and GC/MS: 1 Oxidation by Classical SET Oxidants. In a modification of literature procedures 40,41 Mn(OAc)3‚2H2O (0.42 mmol) was weighed into a 16 × 100 mm screwcap culture tube.…”
