摘要:
A series of mono-, di-, and triruthenium(0) complexes containing a triphenylene ligand, [Ru(eta(4)-1,5-COD)](n)(eta(6n)-triphenylene) (n = 1 (2), 2 (3), 3 (6)) have been prepared by the ligand exchange reaction of Ru(eta(4)-1,5-COD)(eta(6)-naphthalene) (1) with triphenylene, reduction of Ru(acac)(2)(eta(4)-1,5-COD) (4) with sodium/triphenylene, or hydrogenolysis of Ru(eta(4)-1,5-COD)(eta(6)-1,3,5-COT) (5) in the presence of triphenylene. These triphenylene complexes are interconvertible with each other by addition of a "Ru(eta(4)-1,5-COD)" fragment or free triphenylene.
