“…163 The yield of butadiene reached about 90% with scandium oxide-based catalysts. 164 Metal phosphate catalysts have been also tested. Typical phosphate catalysts are less selective than scandium oxide catalysts, [165][166][167] while one relatively old report using CsH 2 PO 4 /SiO 2 showed a very high 92% yield.…”

“…In the first step, glucose is converted selectively into 2,3-butanediol (BDO) by hydrogenolysis under hydrothermal conditions. In the second step, the double dehydration of BDO under acid catalysis forms BDE . There is no catalytic route for synthesizing trans , trans -muconic acid (MCA) from carbohydrates.…”

Reagentless organic synthesis (ROS) can be envisaged as a corollary of the principles of green chemistry, wherein the reactant molecules undergo chemical transformations under the influence of heat, light, sound, or electricity and afford the desired product without necessitating stoichiometric reagents. The predominantly catalytic processes ensure excellent atom economy and minimize waste formation, making the synthetic strategies inherently green. However, since most starting materials stem from exhaustible resources like petroleum, the processes are not entirely sustainable. Reagents and reactants are often used interchangeably, but utmost care should be taken to minimize or eliminate the use of any chemical or material in a chemical transformation that does not appear in a balanced chemical equation. The ideal disposition would be the reagentless synthesis of chemicals using renewable starting materials. In this regard, biomass is a renewable carbon source with the commercial potential to supplant petroleum in producing fuels, chemicals, and polymers. Even though many chemocatalytic biomass value addition processes can be contemplated as ROS, they are somewhat scattered in the literature and have never been deliberated coherently from this perspective. Integration of ROS with biorenewable starting materials can ensure the much-anticipated all-round sustainability of the organic chemical industry. This unique review discusses the merits of synthesizing fuels and chemicals from biomass components following reagentless synthetic steps, critically analyzes the literature data, identifies the research gaps, and proposes future directives.

A handful of small organics, namely, ethylene, propylene, butadiene, benzene, toluene, xylenes, and methanol, produced from petroleum and other fossilized carbon-based resources, can produce practically all petrochemicals and synthetic organic polymers used in the industrialized societies. The molecules mentioned above, often referred to as primary petrochemicals, must be sourced from renewable carbon feedstock to achieve the long-aspired all-around sustainability in chemical manufacturing. Significant efforts have been devoted to developing efficient chemical–catalytic pathways for selectively converting biomolecules and biopolymers into these petroleum-derived chemical platforms. The processes take advantage of prevalent petrorefinery infrastructure, well-documented synthetic value addition pathways of the chemical platforms, and established markets of the derived products. Relative merits and demerits of various catalytic routes in producing the aforementioned primary petrochemicals from renewable biomass have been deliberated. This review elaborates on the synthetic methodologies available for synthesizing the drop-in replacement of primary petrochemical from renewable biomass, focusing on process selectivity, feedstock selection, and catalyst performance. The critical analyses presented in this review will assist in appraising the research accomplishments to date, identifying the bottlenecks, and realigning the future perspectives.
