Triple -substitution reactions of B(CF) and [(CF)PF] with P(SiMe)
para -Substitution reactions on C 6 F 5 rings of Lewis acids have been exploited to achieve triply substituted derivatives. The reaction of B(C 6 F 5 ) 3 with P(SiMe 3 ) 3 ultimately affords the Lewis acid B(C 6 F 4 P(SiMe 3 ) 2 ) 3 1 . This species binds Lewis bases affording the adducts LB(C 6 F 4...
