  The kinetics of the Hg2+-assisted chloride release from some [MCl(RNH2)5]2+ complexes (M = Co, Cr)

  摘要：

  Activation parameters associated with the Hg2+-assisted chloride release reaction in 50:50 dioxane:aqueous HClO4(I=0.5 M) from [MCI(RNH(2))(5)](2+) at 25 degrees C in the order (k(Hg), M(-1)S(-1);Delta H*,kJ mol(-1);Delta S*,J K-1 mol(-1) are M=Cr,R=H:5.45X10(-2),74.7,-18;M=Cr,R=Me:1.78x10(-3),70.0,-32;M=Cr,R=Et:1.19x10(-3),86.8,-9;M=Cr,R=nPr:7.06x10(-4),96.3,+17;M=Cr,R=nBu:5.30X10(-4),98.0,+21;M=Co,R=H:8.74x10(-2),70.3,-37;M=Co,R=Me:2.40,74.0,+11;M=Co,R=Et:4.95,69.0,0;M=Co,R=nPr:2.59,69.3,-5;M=Co,R=nBu:2.15,70.2,-3. Similar data in aqueous HClO4 (I=1.0 M) are M=Cr,R=H:9.84x10(-2),64.6,-27;M=Cr,R=Me:2.15x10(-3),93.2,+16.5M=Co,R=H:1.40x10(-1),65.1,-42; M=Co,R=Me:5.00,70.4,+5. The trends in activation entropy would rank MCl(RNH(2))(5)](2+) (R not equal H) at essentially the same position on an interchange mechanistic scale, independent of M, and more associatively restricting than [MCl(NH3)(5)](2+).

  Steric effects on the substitution of pentaamine-chromium(III) and -rhodium(III) complexes. Anation reaction rate constants as an indicative of the dissociative shift of the mechanism on crowding the [M(RNH2)5H2O]3+ (M = Rh, R = H, Me, Et, Pr; M = Cr, R = H, Me, Pr) complexes

  摘要：

  The kinetics of the anation reactions of [M(RNH(2))(5)H2O](3+) (M=Rh, R=H, Me, Et, Pr; M=Cr, R=H, Me, Pr) with several ligands (H3PO4/H2PO4-, H3PO3/H2PO3-, CF3COO-, Br-, Cl-, SCN-) have been studied at different temperatures and acidities at I=1.0 M (LiClO4). Results obtained for the anation rate constants and thermal activation parameters are compared with the previously published data for R=H, in order to establish the effects of the amine substituents in the reaction mechanism proposed for the substitution reactions of these complexes. The results obtained are interpreted on the basis of a mechanism where the bond formation process is more important in the substitution on M=Cr complexes than in that of the M=Rh complexes, as already pointed out for the published Delta V-not equal values for the water exchange on these systems. A simple Langford-Gray classification becomes inadequate to describe these situations where the increase of the steric demand of the amine substituents shifts the I-a-I-d classification to the I-d side, although no dramatic changes in the reaction mechanism are found. It is concluded that a More O'Ferrall 'continuous' type of approach to the mechanism classification of the substitution reactions is much more useful in this case.
