Reaction Steps

Bromine was added to a solution of flavanone in carbon tetrachloride at 0° C. The ratio of bromine/flavanone was 1.3 in molar terms. The temperature of the solution was raised to 30° C. and kept there for 1 hour. The temperature of the solution was then raised to 65° C. and kept there for 45 minutes.
