YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In methanol; water; for 0.166667h;pH 6.5; An 8 mL aqueous solution of 1,2-H2bdc (0.2 mmol) was adjusted to pH 6.5 with a dilute NaOH solution, then <strong>[143131-66-2]bbtz</strong> (0.2 mmol) in 5 ml MeOH and CdCl2 (0.2 mmol) in 8 mL H2O were slowly added. The mixed solution was stirred for ten minutes and filtered. Colorless crystals 2 were obtained after the filtrate was left to stand for one week. Anal.

YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In methanol;pH 6.5; A 5 mL MeOH/H2O (3:7, v/v) solution was carefully layered over a 5 mL aqueous solution of Cd(NO3)2*6H2O (0.2 mmol) in a test tube. 1,2-H2bdc (0.2 mmol) in 2 mL water was adjusted to pH 6.5 with a dilute NaOH solution and mixed with <strong>[143131-66-2]bbtz</strong> (0.2 mmol) in 2.5 mL MeOH. Then the mixed solution of 1,2-bdc and <strong>[143131-66-2]bbtz</strong> was carefully layered over the above solution in a test tube. Colorless crystals 1 were obtained after three weeks. Anal.

YieldReaction ConditionsOperation in experiment
With chlorine; In water; for 3h; The phthalic acid (1mmol) dissolved in 20 ml of acid in the aqueous solution, the stirring 1.5 hours later, into the chlorine gas, reaction 3 hours, all the solvent is pumped, by adding ethyl acetate 50 ml, the resulting solution with saturated salt water washing 3 times, the organic phase after separation, the aqueous phase is extracted with twice ethyl acetate (50 ml). The combined organic phase, drying agent, filtration of the drying agent, the solvent evaporation to dryness, to obtain the corresponding ortho and meta-substituted phthalic acid chloride (yield 100%, GC purity (two isomers) 99%).

YieldReaction ConditionsOperation in experiment
94% With L-proline; In ethanol; at 30℃; for 6h; The phthalic acid(1.0 mmol), aryl amine (1.0 mmol), and L-proline (0.5 mmol)were sequentially added in ethanol (5.0 mL) into a rb (roundbottom) 6ask to form a solution. The resultant mixture was stirred at 30C room temperature for six hours. After completion of the reaction, the reaction mixture was then diluted with EtOAc ethyl acetate and washed with water. The organic phase was dried, Fltered, and concentrated to give the pure phthalimide product. Purity of the products was checked by TLC. 2.2.1. N-(4-Methoxyphenyl)isoindoline-1,3-dion1e.
