  Synthesis and structure of pyridine-2-thiolato ruthenium aryls bearing a pendant imine–phenol function

  摘要：

  The reaction of Ru(eta(2)-RL)(PPh3)(2)(CO)Cl (1) with sodium pyridine-2-thiolate (Napyt) has afforded the complexes of the type Ru(eta(1)-RL)(PPh3)(2)(CO)(pyt) (3) in excellent yield (eta(2)-RL is C6H2O-2-CHNC6H4R(p)-3-Me-5, eta(1)-RL is C6H2OH-2CHNC6H,R(p)-3-Me-5 and R is Me, MeO, Cl). The reaction is irreversible and is believed to proceed via cis attack by pyt(-) on an octahedral face. The type 3 species are thermodynamically more stable than the corresponding carboxylates, nitrites and nitrates. Structure determination of the solvate, 3(R = Cl).C6H6.0.5C(6)H(14) has revealed a distorted octahedral RuC2P2NS coordination sphere with the pairs (P, P), (C(aryl), N) and (C(carbonyl), S) defining the three trans directions. The eta(1)-ClL ligand metallated ortho to the phenolic oxygen occurs in the imine-phenol tautomeric form (N...O, 2.639(8) Angstrom) which is consistent with IR and H-1 NMR data. The transformation 1 --> 3 is associated with changes in tautomeric form, hapticity and conformation (in relation to CO) of RL. The Ru(eta(1)-ClL) fragment excluding the pendant C6H4Cl(P) group is nearly coplanar (dihedral angle 6.1degrees) with the Ru(pyt) plane. The Ru-S distance, 2.524(1) Angstrom, is longer than usual due to steric reasons. The type 3 complexes display a quasi-reversible Ru(III)/Ru(II) couple near 0.6 V versus SCE.

  in the precursor complex 3(Me). The Ru−C(aryl) distance is also longer in 4(Me) by 0.04 Å. Thus both the bonds are activated by isonitrile insertion and the transformation 4 → 5 occurs spontaneously with C−C bond formation via aryl migration attended with isonitrile elimination, the reaction following first-order kinetics. The activation parameters determined for the 4(Cl) → 5(Cl) reaction are ΔH⧧

  The insertion of HOCH2C drop CH (ha) into the Ru-C bond of Ru-II(RL1)(PPh3)(2)(CO)Cl, 1, has afforded Ru-II(RL3)(PPh3)(2)(CO)Cl, 3, which has been structurally characterized. Insertion rates in CH2Cl2-MeOH for ha as well as for PhC drop CH (pa), which inserts similarly into 1 affording Ru-II(RL2)(PPh3)(2)(CO)Cl, 2, are proportional to the product of the concentrations of alkyne and methanol. The insertion rate of ha is nearly 5 times faster than that of pa, and for a given alkyne the rate increases as R becomes more electron-withdrawing (OMe < Me < Cl). A reaction model implicating the adduct 1 . MeOH, which binds and activates the alkyne via displacement of MeOH, is proposed.
