Abstract

Title compound (I) was obtained from photolysis of (C5H5)Ru(PPh3)H3. The dimer mol. of I possesses point symmetry with the symmetry center on the middle of Ru-Ru bond. Each Ru atom bonded to one Ru atom, one cyclopentadienyl ring, one PPh3, and two bridged hydride ligands. The monomer form of the dimer is a 16-electron species similar to the proposed intermediate in C-H bond activation reaction, e.g. (C5Me5)Ir?PMe3). Here the 16-electron species were catched in the dimer form, giving an experimental evidence to the proposed mechanism of C-H bond activation reaction by organometallic hydrides. The possible path for the formation of I was also suggested.

Key words: CRYSTAL STRUCTURE DETERMINATION, REACTION MECHANISM, TRIPHENYLPHOSPHINE, PHOTOLYTIC REACTION
