The development of Green Chemistry inevitably involves the development of green reagents. In this review, we highlight that Cp 2 TiCl is a reagent widely used in radical and organometallic chemistry, which shows, if not all, at least some of the 12 principles summarized for Green Chemistry, such as waste minimization, catalysis, safer solvents, toxicity, energy efficiency, and atom economy. Also, this complex has proved to be an ideal reagent for green C−C and C−O bond forming reactions, green reduction, isomerization, and deoxygenation reactions of several functional organic groups as we demonstrate throughout the review.

A simple, mild and safe reduction of furfural to furfuryl alcohol by the Mn/2,4,6‐Coll.HCl/H2O system is described. An experimental study on the role played by each of the reagents involved in this reduction and DFT calculations are reported. With the aim to provide an explanation for the results obtained, a complete mechanism is proposed.
