General procedure: As shown as the synthetic protocol A in Scheme 2, compounds 1-11 were synthesized following literature description [16] with m-methoxyphenol, p-methoxyphenol, resorcinol, and hydroquinone as reagents. One hydroxyl group in resorcinol and hydroquinone was protected by tert-butyldimethylsilyl chloride.

The mixture was diluted with CH2Cl2 and washed by saturated NaHCO3 and water. The organic phase was dried over anhydrous Na2SO4, and the solvent was removed under vacuum. The residue was purified by column chromatography with CH2Cl2 as the eluent to afford thiophthalimides as colorless solid. The following cycloaddition reactions were carried out in dry CHCl3 solution of thiophthalimides (~ 0.1 M) and styrenes (2 equiv.) or vinyl ferrocene (2 equiv.) and freshly distilled (C2H5)3N (2 equiv.) at 60 ¡ãC. The reaction was finished with thiophthalimides not detected by TLC. Then, the solvent was evaporated under vacuum pressure, and the residual solid was purified with column chromatography to afford silylated adducts. The desilylation operation was performed in dry tetrahydrofuran (THF) solution containing 0.04 M aforementioned adducts at 0 ¡ãC, to which a solution of (n-C4H9)4NF*3H2O in THF (1 equiv. for each protective group) was added. The reaction was finished with the reagent not detected by TLC, and then the mixture was diluted with ethyl acetate and washed with saturated NH4Cl and water. The organic layer was dried over anhydrous Na2SO4, and the solvent was evaporated under vacuum pressure. The residue was purified with column chromatography to afford thiaflavans.

Iron(III) acetylacetonate, cas is 14024-18-1,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.

General procedure: Monodisperse synthetic Fe1-xMgxFe2O4 (x=0, 0.1, 0.2, 0.3, 0.4, & 0.5) nanospheres were synthesized by recently developed solvothermal reflux method using high boiling point organic solvents mixture as reaction solvent [14,15]. Iron(III) acetylacetonate or Fe(C5H7O2)3 (solid, 97 %, Sigma-Aldrich), Magnesium acetylacetonate or Mg(C5H7O2)2 (solid, 97 %, Aldrich) were used as metal precursors. Benzyl ether (liquid, 98 %, Aldrich, boiling point (bp): 298C) and oleylamine (liquid, 70 %, Aldrich, bp: 364C) solvents mixture as reaction solvent, and oleic acid (liquid, 65 %, SDFCL, bp: 360C) as surfactant were used. To synthesize 0.5g of target composition compound, 40mL of benzylether (BE) and 10mL of oleylamine (OAm) solvents mixture were taken as reaction solvent in three neck round bottom (RB) flask (250mL). The mixture was stirred with magnetic stirrer for 10min. to make it homogeneous. Metal precursor powders were finely grounded to enhance their decomposition. Stoichiometric metal precursor fine powders were added to the reaction solvents mixture. The mixture was stirred for 10min. to make homogeneous solution. Then 5mL of oleic acid (OA) (?2.5 times of metal cations mols) was added. The resultant reactants mixture was heated to boiling point of the solvent mixture (300C) by electric heating mantle at 5C/min ramp. The boiling solvents produce natural gas bubbles. The reaction was carried out for 1h at this temperature and then naturally cooled the RB flask to room temperature. To precipitate crystallined ferrite nanoparticles, anti-solvent such as ethanol was added to the reaction mixture. The precipitated nanoparticles were separated by sedimentation principle through centrifugation. The nanoparticles were redispersed in good solvents such as n-hexane. To further purify the nanoparticles from residual organic molecules (surfactant), the redispersed particles were precipitated, separated and redispersed by the above procedure, at least two times.

The chemical industry reduces the impact on the environment during synthesis,14024-18-1,Iron(III) acetylacetonate,I believe this compound will play a more active role in future production and life.
