Carbon dioxide-to-methanol single-pot conversion using a C-scorpionate iron(II) catalyst

The highly efficient eco-friendly synthesis of methanol (44% yield, TONs up to 2.3 x 10(3)) directly from carbon dioxide is achieved by using H-2 and the iron(II) scorpionate catalyst [FeCl2{kappa(3)- HC(pz)(3)}] (pz = pyrazol-1-yl) in a solvent- or amine-free mild new protocol.
