YieldReaction ConditionsOperation in experiment
61% With potassium carbonate; In N,N-dimethyl-formamide; at 80℃; for 2h; A typical synthetic procedure is as follows. 1,7-dibromo perylene diimide (1, 77 mg, 0.1 mmol) was dissolved into 5 mL of dimethylformamide (DMF). To which alkyl alcohol (R-OH, 0.5 mmol) and potassium carbonate (K2CO3, 70 mg, 0.5 mmol) were added. The resulted mixture was then allowed reacted under 80C for 1-4 hours. The reaction mixture was then powered into 15 mL water and the red solid was then re-dissolved in 20 mL dichloromethane (DCM) and washed with 1N hydrochloric acid and then water each for 3 times. Then, DCM layer was dried over Na2SO4. After removal of DCM, the residue was applied to chromatography with CH2Cl2/ethyl acetate (100:0-100:2) as eluents to afford the desired products 4.

YieldReaction ConditionsOperation in experiment
97% With tetrabutylammonium bromide; In N,N-dimethyl-formamide; at 80℃; for 1.83333h; General procedure: A mixture of alcohol (1 mmol), 1,2-phenylenediamine or 2-aminothiophenol(1 mmol), Pd(II)Cl2-BTPMNPs (0.019 g, containing 0.09mol% Pd) and (1 mmol) tetrabutylammonium bromide (TBAB, 0.01 g)in DMF (5 mL) in a round-bottomed flask equipped with a condenser wasstirred at 80 C. The progress of the reaction was monitored by TLC(eluent: n-Hexane/EtOAc, 4: 1 for benzimidazoles and n-Hexane/EtOAc, 6: 1 for benzothiazoles). The catalyst was separated by permanentmagnet and washed with EtOAc (10 mL). The crude product waspurified by recrystallization from EtOAc or EtOH to afford the purebenzimidazole. The benzothiazoles was obtained by recrystallizationfrom n-hexane/EtOAc (10: 1).
79% With anhydrous sodium carbonate; In neat (no solvent); at 120℃;Green chemistry; General procedure: Typically, o-phenylenediamine (1.3 mmol) or 2-aminothiophenol (1 mmol), benzyl alcohols (1 mmol), Na2CO3 (20 mol%), and Pd-NPs/Cu2(BDC)2(DABCO) (20 mg, 0.01 mol%) were added to a round-bottom flask. The reaction mixture was heated to 120 Cand stirred at for the appropriate time in air (TLC monitoring). Ethyl acetate was added to the reaction mixture and catalyst was filtered. For the purification of impure products, chromatography on silica gel was performed (EtOAc:Hep. (1:6)). The entire products characterized by melting point, CHN, 1H-NMR and13C-NMR spectroscopy.
79% With potassium-t-butoxide; In toluene; at 20 - 110℃; for 48h; At room temperature, add o-aminothiophenol 1a (0.6 mmol), toluene solvent and 4-methylbenzyl alcohol 2e (0.2 mmol) to the reactor in turn, stir at room temperature to fully dissolve them, and add to Example 1 in turn The prepared HKUST-1-400 catalyst (20mg), potassium tert-butoxide (0.2mmol), after dissolving, continue the reaction and place it at 110C for 2 days. After the completion of the reaction is detected by TLC, the Cu-MOF derivative material is filtered out first The HKUST-1-400 catalyst was then subjected to column chromatography to obtain the target compound 3e with a yield of 79%.

Typically, a mixture of oaminothiophenol(0.1 mmol) and alcohol (0.3 mmol) in acetonitrile(CH3CN, 2 mL) was saturated with O2 before the mixture wastransferred into a 10 mL tube containing 10 mg of MOFs. The suspensionwas irradiated with a 300WXe lamp equipped with a UVcutfilter to remove all irradiations with wavelengths less than420 nm and an IR-cut filter to remove all irradiations with wavelengthsgreater than 800 nm. After the reaction, the suspensionwas filtered through a porous membrane (diameter 20 μm) andthe products were analyzed by GC-MS and GC-FID (ShimadzuGC-2014) with an HP-5 capillary column. The reaction, scaled upby 10 times, was conducted under similar conditions in a homemadereactor. A mixture of o-aminothiophenol (1 mmol) and benzylalcohol (3 mmol) in CH3CN (20 ml) saturated with O2 wastransferred to the homemade reactor containing 100 mg of MIL-100(Fe). The reactor was irradiated with a 300W Xe lampequipped with both a UV-cut filter and an IR-cut filter.
