“…Nagpure et al. explored hydrogenolysis of HMF to DMF over Ru containing hydrotalcite(HT) catalysts and achieved complete conversion of HMF to DMF at 220 °C in 4 h . In this study, different solvents, such as protic (2‐propanol), aprotic (THF) and 1,2‐dimethoxyethane (1,2‐DME), as well as non‐polar (toluene), were explored.…”

Catalytic transformation of biomass‐derived compounds to different platform chemicals and liquid fuel is a prominent way to reduce the global dependence on fossil resources. In past few decades, biomass‐derived furans such as 2‐furfuraldehyde (furfural) and 5‐hydroxymethyl‐2‐furfural (HMF) have received outstanding attention because of their wide applications in the production of various industrially important value‐added chemicals and fuel components. Various catalytic systems and methodologies have been extensively explored for the transformation of these furans to a wide range of products including open ring diketones, ketoacids, alcohols and long chain alkanes. This Review is aimed to provide an extensive overview of the recent developments of several high‐performing heterogeneous catalysts for the catalytic upgradation of the key biomass‐derived furans (furfural and HMF) to value‐added chemicals. Moreover, the role of these catalysts in the catalytic transformations including hydrogenation, decarbonylation, oxidation, hydrogenolysis and ring opening reactions, and the mechanistic pathways are also highlighted in this Review.

This work provided the first example of selective hydrodeoxygenation of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) over heterogeneous Fe catalysts. A catalyst prepared by the pyrolysis of an Fe-phenanthroline complex on activated carbon at 800 °C was demonstrated to be the most active heterogeneous Fe catalyst. Under the optimal reaction conditions, complete conversion of HMF was achieved with 86.2 % selectivity to DMF. The reaction pathway was investigated thoroughly, and the hydrogenation of the C=O bond in HMF was demonstrated to be the rate-determining step during the hydrodeoxygenation, which could be accelerated greatly by using alcohol solvents as additional H-donors. The excellent stability of the Fe catalyst, which was probably a result of the well-preserved active species and the pore structure of the Fe catalyst in the presence of H , was demonstrated in batch and continuous flow fixed-bed reactors.

“…The development of such iridium complexes may broaden the scope as catalysts and may act as model molecules for biological, photophysical and chemical activities , . In other words, in recent years, great attention has been focused on the conversion of biomass into valuable chemicals, in which group VIII metal complexes play a vital role , , . In particular, hydrogenation of levulinic acid to γ‐valerolactone and 1,4‐pentanediol has a significant role as a green solvent, as well as an important intermediate in several fine chemical syntheses , .…”

Here we report the preparation of first examples of iridium‐based organometallic macromolecules, viz., iridium‐tetra (4‐carboxyphenyl)porphyrin (IrTCPP), iridium‐calix[4]pyrrole (IrCP) iridium‐tetraphenylporphyrin (IrTPP), which are effective catalysts for hydrogenation of levulinic acid (LA) to γ‐valerolactone (GVL) and 1,4‐pentanediol under base free conditions. The turnover number in the range of 1220–2850 is evident for the chosen reaction using iridium macromolecule based catalysts. The heterogenization of homogeneous IrTCPP, IrCP, and IrTPP result in stable reactivity of the catalysts for several runs.
