Small molecule conversion, complexes coordination sphere

We considered the possibility of the positive effect of small amounts of water on the rate of the transformation of iron complexes with (L = R NBr, 18C6) and, probably, on the parameters and C in the ethylbenzene oxidation, catalyzed Fe(in)(acac)3 + L. Outer sphere coordination of H O molecules may promote the stabilization of intermediate zwitter-ion L (L M(L ) 02 and as a consequence the increase in the probability of the regioselective addition of 0 to nucleophilic y-C atom of (acac) ligand one e qrected. It is well-known that the stability of zwitter-ions increases in the presence of the polar solvents [114]. The H - bond formation between H2O molecule and zwitter-ion may also promote the proton transfer inside of the zwitter-ion followed by the zwitter-ion conversion into the products via Scheme 4 [114, 115]. It is known the cases of the increase in the ratio...
