Sole, Roberto published the artcileSynthesis of 2-Alkylaryl and Furanyl Acetates by Palladium Catalysed Carbonylation of Alcohols, COA of Formula: C9H10O2, the main research area is aralkyl alc methanol carbon monoxide palladium catalyst methoxycarbonylation; alkylaryl acetate preparation.
In this paper, the reaction between benzyl alc., chosen as a model substrate, CH3OH and CO was tested in the presence of a homogeneous palladium catalyst, an activator (isopropenyl acetate (IPAc) or di-Me carbonate (DMC)) and a base (Cs2CO3). The influence of various reaction parameters such as the CO pressure, ligand and palladium precursor employed, mmol% catalyst load, temperature and time were investigated. The results demonstrate that decreasing the CO pressure from 50 bar to 5 bar at 130°C for 18 h increases yields in benzyl acetate from 36% to over 98%. Further experiments were performed in the presence of piperonyl and furfuryl alc., interesting substrates employed for the synthesis of various fine chems. Moreover, furfuryl alc. is a lignocellulosic-derived building block employed for the synthesis of functionalized furans such as 2-alkylfurfuryl acetates. Both the alcs. were successfully transformed in the corresponding acetate (yields above 96%) in rather mild reaction conditions (5-0.01 mol% catalyst, 5-2 bar CO pressure, 130°C, 4-18h), demonstrating that the alkoxycarbonylation of alcs. represents a promising sustainable alternative to more impactful industrial practices adopted to date for the synthesis of alkylaryl and furfuryl acetates.
