N-Fluorobenzenesulfonimide → 1-Fluoroanthracene

Participants

Reaction Conditions

Reaction Steps

1.2 millimoles n-butyl lithium were dropped into a solution of 1 millimole bromoanthracene in 5 milliliters diethyl ether at 5° C. The solution was cooled to 0° C, was stirred for 1 hour, and then was cooled further to -78° C.; 1.2 millimoles N-fluorobenzenesulfonimide prepared according to Example 1 above in 5 milliliters tetrahydrofuran were dropped into the mixture which was stirred for 1 hour. The temperature was allowed to rise to 20° C. while stirring was continued. The reaction mixture was quenched by pouring into saturated ammonium chloride solution and extracted with diethyl ether. Fluoroanthracene was obtained in 76% yield.
