title: Reactivity of an intramolecular fluorophosphonium fluoroborate.
abstract: The reactions of the intramolecular frustrated Lewis pair-adduct Ph(2) PC(p-Tol)=C(C(6) F(5))B(C(6)F(5))2 (CNtBu) with XeF(2) gave Ph(2)P(F)C(p-Tol)=C(C(6)F(5))B(F)(C(6)F(5))(2)(3). This species reacts with two equivalents of Al(C(6)F(5))(3)⋅C(7)H(8) producing the salt, [Ph(2)P(F)C(p-Tol)=C(C(6)F(5))B(C(6)F(5))(2)][F(Al(C(6)F(5))(3))(2)] (4), whereas reaction with HSiEt(3)/B(C(6)F(5))(3) gave Ph(2) P(F)C(p-Tol)=C(H)B(C(6)F(5))(3) (5). The photolysis of 3 resulted in aromatization affording the phenanthralene derivative Ph(2) P(F)C(p-Tol(o-C(6)F(4)))=CB(F)(C(6)F(5))(2) (6).
