For many of the applications, immobilization of carbohydrates like mannose onto MSNs is a crucial aspect, and in most cases, mannose moieties are connected through <i>O</i>-glycosidic linkages that are susceptible to acidic/enzymatic hydrolysis. To generate a stable mannose-functionalized MSN, we designed a novel <i>C</i>(14)-<i>α</i>-mannosylated tetradeca-1-yne. The key steps involved in the synthesis of <i>C</i>-mannosylated alkyne are C1-alkynylation of tri-<i>O</i>-acetyl-D-glucal with 1-trimethylsilyl-tetradec-1-yne, followed by stereoselective dihydroxylation and the isomerization of the internal triple bond to a terminal position. This mannose ligand was then immobilized onto azidopropyl-functionalized SBA-15 through the Cu(I)-catalyzed azide-alkyne click (CuAAC) reaction.

This work investigates the utilization of a unique Ni–Co/Al-SBA-15 heterogeneous catalyst to convert eugenol into 4-propylphenol, a multifunctional chemical with use as an antioxidant, flavouring agent, and disinfectant.
