摘要:
The 16-electron. live-coordinate fluoro complex [RuF(dppp)(2)]PF6 (1a; dppp = propane-1,3-diylbis[diphenylphosphine] smoothly reacts with 19-diphenylallyl bromide (=1,1'-(3-bromoprop-1-enc-1,3-diyl)bis[benzene]) in dry CDCl3 to give 1,3-diphenylallyl fluoride and [RuBr(dppp)(2)](+) in nearly quantitative yield. Under similar conditions, bromide for chloride)/fluoride exchange also occurs with chlorotriphenylmethane, bromodiphenylmethane, and tert-butyl bromide. The crystal structure of 1a is reported.
