To address the aviation sector's growing carbon footprint, this study presents a novel route for producing sustainable aviation fuel precursors via acid-catalyzed Friedel-Crafts alkylation of wood-derived lignin monomers with furfuryl alcohol. Using guaiacol as a model compound, key catalytic requirements were investigated in batch mode. Although heterogeneous zeolites showed initial promise, pore blocking by oligomerized furfuryl alcohol limited performance, leading to the selection of para-toluenesulfonic acid as an effective homogeneous catalyst. A fed-batch strategy was employed to suppress oligomerization by controlling furfuryl alcohol concentration. The resulting alkylated products, structurally aligned with conventional kerosene, were further upgraded via metal-catalyzed hydrodeoxygenation, achieving final overall yields up to 92 C%.

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
