| Abstract: | The 16-electron, five-coordinate fluoro complex RuF(dppp)2]PF6 ( 1a ; dppp=propane-1,3-diylbisdiphenylphosphine] smoothly reacts with 1,3-diphenylallyl bromide (=1,1′-(3-bromoprop-1-ene-1,3-diyl)bisbenzene]) in dry CDCl3 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. |
