Using synthetic methods and pentafluorophenyllithium for producing boric acid tetrakis pentafluorophenyl

摘要

A pentafluorophenyl compound (1) is reacted with an alkyl lithium compound (6) in a reaction zone (5), 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 (5) at any time. The product may be directly discharged from the reaction zone for combination with another reactant (10).
