Abstract

First ruthenium complexes with a ferrocene-based pincer ligand were synthesized. The cyclometallation of 1,3-bis[(di-tert-butylphosphino)methyl]ferrocene with RuCl2(DMSO)4 in 2-methoxyethanol afforded the RuCl(CO)[{2,5-(But2PCH2)2C5H2}Fe(C5H5)](RuCl(CO)\([^{Bu^t } P,C,P^{Fe} ]\)) complex (5). Complex 5 reversibly binds CO to form the RuCl(CO)2\([^{Bu^t } P,C,P^{Fe} ]\) complex (6). The analogous reaction in the presence of NaBAr′4 (Ar′ = 3,5-(CF3)2C6H3) produced the cationic complex {Ru(CO)2\([^{Bu^t } P,C,P^{Fe} ]\)}BAr′4 (7). The structures of complexes 5 and 7 were established by single-crystal X-ray diffraction. The X-ray diffraction study revealed an agostic interaction between one of the C-H bonds of the axial (exo-oriented with respect to the ferrocene iron atom) tert-butyl group and the Ru atom in complexes 5 and 7.
