Dimethylformamide → 2,3,6,7,10,11-Hexakis[2-(2-methoxyethoxy)ethoxy]triphenylene

Participants

Reaction Steps

In a reaction vessel, 15 ml of dry N,N-dimethylformamide (DMF) and 0.77 g (19.3 mM) of NaH (60 W in mineral oil) were placed. Then, 0.92 g (2.84 mM) of 2,3,6,7,10,11-hexahydroxytriphenylene was added thereto on a water bath, and after 1 hour of stirring, a mixture liquid of 6.4 g (23.3 mM of 1,4,7-trioxaoctyl p-toluenesulfonate and 5 ml of dry DMF was added dropwise thereto, followed by 5 hours of stirring at 80° C. After the reaction, water was added to the reaction mixture, followed by extraction two times with toluene. The extract was washed with water and dried with anhydrous sodium sulfate, followed by distilling-off the solvent and purification three times by silica gel column chromatography (eluent: chloroform to obtain 0.14 g (0.15 mM) of 2,3,6,7,10,11-hexa(1,4,7-trioxaoctyl)triphenylene (Yield: 5%), which showed a melting point of 54 ° C.
