Amines, coordinated Exchange with solvent

It has been noted that a positive activation volume (8.0 cm moP ) for the incorporation of Co " into N-methyltetraphenylporphyrin in DMF is consistent with an Id mechanism. The kinetics of the dissociation of the five-coordinate cobalt(II) complex of tris(2-dimethylaminoethyl)amine in solutions of chloroacetic acid in DMF and other solvents have been repor-ted, but no firm conclusions are drawn concerning the mechanism. The formation of the pentane-2,4-dione complex of Co(II) in aqueous solution has been studied/ and the values of kf for the reaction of the enol and keto tautomers (respectively, 136 and 0.84dm mor s 25 C, / = 0.5 mol dm ) found to be considerably lower than those predicted on the basis of the solvent exchange rate for this metal. [Pg.254]
