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 (CN t Bu) 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 ).
