Type: article
Abstract: ABSTRACT Glycerol, the byproduct of a multi‐ton biofuel industry, is a cheap and useful feedstock for value‐added chemical transformations. The conversion of glycerol to lactic acid has been realized using pincer complexes, mainly based on 4d and 5d transition metals. Herein, a well‐defined, nonsymmetrical PN 3 P‐Fe complex ( Fe‐1 ) was synthesized and characterized. Single‐crystal x‐ray diffraction (SC‐XRD) revealed a distorted square pyramidal geometry, while spectroscopic analysis and the Evans method confirmed a high‐spin Fe(II) center. The complex Fe‐1 performed glycerol to lactate transformation with an excellent yield and selectivity of up to 87%. Furthermore, a series of control experiments demonstrated the molecular nature of the transformation and elucidated the role of the catalyst in the organic cascade.
