Abstract
The reaction of (CF3)2C:C(F)CF2CF3 or CF3CF:CF2 with cis-Ru(dmpe)2H2 (dmpe = Me2PCH2CH2PMe2) affords the bifluoride fluoride complex cis-Ru(dmpe)2F(F.HF), whereas reaction with Ru(dcpe)2H2 (dcpe = (C6H11)2PCH2CH2P(C6H11)2) yields [Ru(dcpe)2H]+ with [(CF3)2C:C(O)CF2CF3]- as the anion. Thus the pathways for C-F bond activation of the perfluoroalkenes by Ru(P-P)2H2 are highly dependent upon the phosphine substituents. Cis-Ru(dmpe)2F(F.HF) and [Ru(dcpe)2H][(CF3)2C:C(O)CF2CF3] were characterized by x-ray crystallog.
