| Abstract |
The C-scorpionate iron(II) complexes [FeCl2\kappa(3)-HC(pz)(3)\](1) (pz = pyrazol-1-yl), Li[FeCl2\kappa(3)-SO3C(pz)(3)\] (2) and the new [FeCl2\kappa(3)-HOCH2C(pz)(3)\] (3) act as catalysts for the hydrocarboxylation of cyclohexane (with CO and H2O) to cyclohexanecarboxylic acid in a remarkable yield (up to 60\%) and under mild conditions. The catalysts selectivity for the acid can be tuned by CO pressure, catalyst amount and reaction temperature. Complex [FeCl2\kappa(3)-HC(pz)(3)\] (1) provides the most effective catalyst requiring low CO pressure. This work constitutes an unprecedented use of iron complexes as catalysts for the hydrocarboxylation of alkanes. |
