2-(1H-pyrrol-2-ylmethyl)-1H-pyrrole Chemical Properties,Usage,Production
Chemical Properties
gray solid
Uses
Dipyrromethane is a new organic reagent for the synthesis of gold nanoparticles.
Definition
ChEBI: Dipyrromethane is a dipyrrole.
Synthesis
109-97-7
50-00-0
21211-65-4
The general procedure for the synthesis of di(1H-pyrrol-2-yl)methane from pyrrole and formaldehyde was as follows: paraformaldehyde (0.5 g, 16.7 mmol) was added to pyrrole (118 mL, 1.67 mol) as a solvent, followed by the addition of catalyst indium(III) chloride (370 mg, 1.67 mmol). The reaction mixture was stirred at room temperature for 10 h under argon protection. Subsequently, the reaction system was warmed up to 55 °C and stirring was continued for 6 hours. After completion of the reaction, sodium hydroxide (NaOH, 0.2 g, 83.5 mmol) was added and stirred for 4 hours. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by column chromatography using dichloromethane: hexane (1:1, v/v) as eluent to afford 2.05 g (yield: 84%) of the target compound di(1H-pyrrol-2-yl)methane as a white solid.
