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