  Synthesis and characterization of ruthenium, rhenium and titanium formate, acetate and trifluoroacetate complexes. Correlation of IR spectral properties and bonding types

  摘要：

  New formate (1-3; 4b, 6 and 7), acetate (8, 9) and trifluoroacetate (12, 13 and 15) complexes have been synthesized and characterized by elemental analysis and by IR and H-1 and C-13 NMR spectroscopies. New data or new synthetic procedures are provided for several known complexes (4a, 5, 19, 11 and 14). X-ray structural data for cis-Ru(bpy)(2)(CO)(OCHO)(PO2F2) (4b) clearly identify the eta(1)-bound formate ligand bound to an octahedral ruthenium center and the data for fac-Re(CO)(3)(PPh3(OCOMe) (9) show an eta(2)-bound acetate ligand bound to an octahedral rhenium center. Infrared spectral data for four types of formate complexes, three bonding types of acetates and the two known types of trifluoroacetate ligands are discussed. Comparisons of the v(OCO) bands for the carboxylate ligands in all of the complexes show that these bands are useful in identifying the bonding type of each carboxylate ligand.

• Hydride Transfer Reactions of Transition Metal Hydrides:  Kinetic Hydricity of Metal Carbonyl Hydrides

  Hydride transfer from neutral transition metal hydrides (MH) to Ph3C+BF4- gives M-FBF3 and Ph3CH. The rate law −d[Ph3C+BF4-]/dt = k[Ph3C+BF4-][MH] was established from kinetic measurements using stopped-flow methods. Second-order rate constants determined in CH2Cl2 solution at 25 °C range from kH− = 7.2 × 10-1 M-1 s-1 to kH− = 4.6 × 106 M-1 s-1. The order of increasing kinetic hydricity is (C5H4CO2Me)(CO)3WH

  从中性过渡金属氢化物 (MH) 到 Ph3C+BF4- 的氢化物转移得到 M-FBF3 和 Ph3CH。速率定律 -d[Ph3C+ -]/dt = k[Ph3C+ -][MH] 是根据使用停流方法的动力学测量建立的。在 25 °C 的 CH2Cl2 溶液中测定的二阶速率常数范围从 kH− = 7.2 × 10-1 M-1 s-1 到 kH− = 4.6 × 106 M-1 s-1。增加动力学水合度的顺序是 (C5H4CO2Me)(CO)3WH < (CO)5MnH < Cp*(CO)3CrH < Cp(CO)3WH < HSiEt3 < cis-(CO)4(PCy3)MnH < cis-(CO) )4(PPh3)MnH < (C5H4Me)(CO)3WH < Cp(CO)3MoH < Cp*(CO)3WH < (茚基)(CO)3WH < (CO)5ReH < Cp*(CO)3MoH

  The kinetics of hydride transfer from a series of metal hydrides (MH) to Ph(3)C(+)BF(4)(-) (producing Ph(3)-CH and M- - -FBF3) have bean studied by stopped-flow methods in CH2Cl2 solution. Second-order rate constants at 25 degrees C span 5 orders of magnitude in kinetic hydricity, ranging from k = 5.0 x 10(1) M(-1) s(-1) for HMn-(CO)(5) to k = 4.6 x 10(6) M(-1) s(-1) for trans-HMo(CO)(2)-(PMe(3))Cp.
