ИСТИНА

The prepn. method of chlorobis(pentafluorophenyl)borane includes: dissolving bis(pentafluorophenyl)borane in solvent (dichloromethane, chloroform, etc.), introducing hydrogen chloride gas, stirring under sealed condition, heating to b.p. of solvent ±> 5°C under normal pressure, reacting for 12-24 h, and removing solvent to obtain final product. The prepn. method has simple process and high yield, and chlorobis(pentafluorophenyl)borane is a very important borane intermediate for the synthesis of boron-contg. compds.
