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

Procedure: To a stirring solution of 3-Bromo indan-1-one (400 mg, 1.90 mmol) in DMF (5 ml) was added sodium azide (1.98 g, 0.03 mol). The reaction was allowed to stir at room temperature for 15 mins. The product was partitioned between water (10 ml) and ether (10 ml). The ether layers were combined and the crude reaction mixture was passed through a plug of flash silica, eluting with petroleum ether:ethyl acetate (9:1). The product was isolated as an orange oil (283 mg, 86%). The product was partitioned between water (10 ml) and ether (10 ml) the crude reaction mixture eluting with petroleum ether:ethyl acetate (9:1)

Procedure: 3-Bromoindan-1-one (1.5) was dissolved in diethyl ether (10 ml). The temperature was kept at +2-+4 while TEA (2.7 ml) was added. The resulting mixture was further stirred at +2-+4 for 2 hours. The precipitated salt was filtered off and the filtrate evaporated. The crude inden-1-one was used for further reaction without purification. Yield was 0.9 g. was added The precipitated salt was filtered off the filtrate evaporated The crude inden-1-one was used for further reaction without purification

Procedure: 1-Indanone (1 g) and NBS (1.4 g) was mixed with dry CCl4 (20 ml). A catalytic amount of AlBN was added and the mixture was refluxed for 30 minutes and excited with light using 250 W lamp. The mixture was cooled in an ice bath and filtered. The filtrate was concentrated in an evaporator and used without further purification for the next step. Yield was 1.5 g. the mixture was refluxed for 30 minutes The mixture was cooled in an ice bath filtered The filtrate was concentrated in an evaporator used without further purification for the next step
