Synthesis of a ruthenium complex of a cyclic trifunctional #eta#~6, #eta#~1, #eta#~1-arene-diphosphine ligand by intramolecular dehydrofluorinative carbon-carbon coupling

摘要

Treatment of the ruthenium complex cation [(#eta#~6-C_6H_3Me_3-1,3,5)(RuCl(dfppe)]~+ {dfppe = (C_6F_5)_2PCH_2CH_2P(C_6F_5)_2} with proton sponge yields [{#eta#~6, #eta#~1,#eta#~1-C_6H_3Me-5-[CH_2-2-C_6F_4P(C_6F_5)CH_2]_2-1,3}RuCl]~+ by stepwise intramolecular dehydrofluorinative carbon-carbon coupling.
