Water → Triphenylene

참여 물질

반응 단계

2.87 mmol of the o-terphenyl derivative, 0.14 mmol of Pd(OAc)2 and 5.7 mmol of K2CO3 are heated in 7 ml of DMA at 135° C. for 24 hours under a nitrogen atmosphere. The reaction mixture is cooled, treated with 5 ml of water and extracted with dichloromethane. The organic phase is dried, the solvent is removed under reduced pressure and the residue is purified by means of a short silica gel column (dichloromethane). After column chromatography (dichloromethane/hexane, 2:1), the desired triphenylene derivative (IIa) is obtained in from 35 to 40% yield.
