1,2-bis(2-bromoethyl)benzene

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of 6-bromo-indan-1-one (300 mg, 1.43 mmol), 1,2-bis(2-bromoethyl)-benzene (414.3 mg, 1.43 mmol) in THF (10 mL) was added NaH (114 mg, 2.86 mmol) at room temperature, the mixture was refluxed for 2 hours. The mixture was quenched with water, concentrated, then extracted with DCM, washed with brine, dried over Na2SO4, concentrated to 6′-bromo-5,6,8,9-tetrahydrospiro[benzo[7]annulene-7,2′-inden]-1′(3′H)-one (20 mg, 5%). the mixture was refluxed for 2 hours The mixture was quenched with water concentrated extracted with DCM washed with brine dried over Na2SO4 concentrated to 6′-bromo-5,6,8,9-tetrahydrospiro[benzo[7]annulene-7,2′-inden]-1′(3′H)-one (20 mg, 5%)
