1-(4-bromophenyl)prop-2-en-1-ol

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 81 ml of a 1.6 molar solution of vinylmagnesium bromide in THF are dripped at -10° C. into a solution of 20.0 g of 4 bromobenzaldehyde in 300 ml of absolute THF. After addition the mixture is stirred for 60 minutes at 0° C., poured into ice water and extracted with ethyl acetate. After chromatography on Al2O3 with hexane/ethyl acetate 18.6 g of 4-(1-hydroxy-2-propenyl)-bromobenzene are obtained in the form of colorless oil. After addition the mixture extracted with ethyl acetate
