ABSTRACT:
Procedures are disclosed which preclude significant safety hazards in the production of bulk quantities pentafluorophenyl lithium. A pentafluorophenyl compound is reacted with an alkyl lithium compound in a reaction zone, preferably temperature controlled, under conditions such that only a small amount of a predetermined quantity of pentafluorophenyl lithium product is present in the reaction zone at any time. The product may be directly discharged from the reaction zone for combination with another reactant.
