  Ruthenium Hydrides Containing the Superhindered Polydentate Polyphosphine Ligand P(CH₂CH₂P^tBu₂)₃

  摘要：

  The complex RuH2(N-2)(P((2))P-3(tBu)) (1) containing the extremely bulky PP3-type ligand P((2))P-3(tBu) = P((CH2CH2PBu2)-Bu-t)(3) was synthesized by reduction of RuCl2((PP3)-P-2(tBu) (2) with Na/NH3 under a N-2 atmosphere. Like other complexes containing the P(2)P3(tBu) ligand, only three of the four donor phosphines are coordinated, and one of the phosphines remains as a dangling pendant phosphine. Reduction of RuCl2((PP3)-P-2(tBu)) (2) with a range of the more usual hydride reducing agents afforded the previously unknown ruthenium hydride complexes RuHCl(P(2)P3(tBu)) (3), RuH(BH4)((PP3)-P-2(tBu)) (6), RuH(AlH4)(P(2)P3(tBu)) (7), and the ruthenium(II) trihydride K[Ru(H)(3)((PP3)-P-2(tBu))] (8). The ruthenium tetrahydride containing a coordinated H2 ligand RuH2(H-2)((PP3)-P-2(tBu)) (10) was synthesized by exchange of N2 in 1 by H2. Complexes 1, 3, 6, 7, and 8 were characterized by crystallography and multinuclear NMR spectroscopy.

  摘要：

  The synthesis and characterization of the extremely hindered phosphine ligands, P((CH2CH2PBu2)-Bu-t)(3) ((PP3tBu)-P-2, 1), PhP((CH2CH2PBu2)-Bu-t)(2) (PhP(2)p(2)(tBu), 2), and P((CH2CH2CH2PBu2)-Bu-t)(3) ((PP3tBu)-P-3, 3) are reported, along with the synthesis and characterization of ruthenium chloro complexes RuCl2((PP3tBu)-P-2) (4), RuCl2((PhPP2tBu)-P-2) (5), and RuCl2((PP3tBu)-P-3) (6). The bulky (PP3tBu)-P-2 (1) and (PP3tBu)-P-3 (3) ligands are the most sterically encumbered PP3-type ligands so far synthesized, and in all cases, only three phosphorus donors are able to bind to the metal center. Complexes RuCl2((PhPP2tBu)-P-2) (5) and RuCl2((PP3tBu)-P-3) (6) were characterized by crystallography. Low temperature solution and solid state P-31{H-1} NMR were used to demonstrate that the structure of RuCl2((PP3tBu)-P-3) (4) is probably analogous to that of RuCl2((PP3tBu)-P-3) (5) which had been structurally characterized.
