The 16‐electron, five‐coordinate fluoro complex [RuF(dppp) 2 ]PF 6 ( 1a ; dppp=propane‐1,3‐diylbis[diphenylphosphine] smoothly reacts with 1,3‐diphenylallyl bromide (=1,1′‐(3‐bromoprop‐1‐ene‐1,3‐diyl)bis[benzene]) in dry CDCl 3 to give 1,3‐diphenylallyl fluoride and [RuBr(dppp) 2 ] + in nearly quantitative yield. Under similar conditions, bromide (or chloride)/fluoride exchange also occurs with chlorotriphenylmethane, bromodiphenylmethane, and tert ‐butyl bromide. The crystal structure of 1a is reported.
