Yield:111-18-2 78%
Reaction Conditions:
with [1,2,3,4,5-pentamethylcyclopentadiene*Ir(2,2'-bibenzimidazole)Cl]Cl;caesium carbonate at 120; for 12 h;
Steps:
6 N1, N1, N7, N7-tetramethylheptane-1, 7-diamine
1,6-hexanediamine (86 mg, 0.5 mmol), cat. [Ir] (3.2 mg, 0.005 mmol, 1 mol%),Cesium carbonate (81 mg, 0.25 mmol, 0.5 equiv.) and methanol (1 mL) were sequentially added to a 25 mL Kelvin tube.After reacting at a temperature of 120 ° C for 12 hours, it was cooled to room temperature. Rotary evaporation to remove the solvent,The pure target compound was obtained by column chromatography (developing solvent: petroleum ether / ethyl acetate), yield: 78%
