Reaction Steps

This compound was synthesized according to a modified literature procedure.52 A Schlenk tube was charged with 3,6-Bis-[2-(3,4-bis-dodecyloxy-phenyl)-vinyl]-11,12-dinitro-dibenzo[a,c]-phenazine BRK_III—63A (564 mg, 0.43 mmol) and (970 mg, 4.30 mmol) of SnCl2.2H2O and was subjected to vacuum. Under N2, 30 ml of O2-free ethanol was transferred to the reaction mixture, which was heated at 70° C. The color of the reaction mixture did not change after one hour and TLC did not show the conversion of the starting material. Additional 50 ml of O2-free ethanol was added and the mixture was refluxed for 23 hours. The reaction was allowed to cool down to room temperature and was then dropped over ice. The solution was extracted with 3×150 ml of ether. The ether extracts were combined and were dried over MgSO4 and was filtered. The solvent (solution is blue fluorescent) was evaporated under vacuum to yield 122 mg (23% yield) of brown solid. HRMS-MALDI-TOF (M+H): m/z 1251.9535; calcd for C84H123N4O4, 1251.9539.
