4-[(3-oxo-1H-inden-2-ylidene)methyl]benzonitrile

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4-(1-Oxoindan-2-ylidenemethyl)benzonitrile (2.18 g, 8.9 mmol) was dissolved in carbon tetrachloride (40 mL). N-bromosuccinimide (1.58 g, 8.9 mmol) and benzoyl peroxide (100 mg) were added in one portion. Reaction mixture was reflux for 9 h, cooled down; precipitate was filtered off and washed with diethyl ether (10×30 mL) for removal of N-hydroxysuccinimide Precipitate was dried under vacuum, provided pure 15a. Reaction mixture was reflux for 9 h cooled down precipitate was filtered off washed with diethyl ether (10×30 mL) for removal of N-hydroxysuccinimide Precipitate was dried under vacuum
