Das, Kanu; Yasmin, Eileen; Das, Babulal; Srivastava, Hemant Kumar; Kumar, Akshai published the artcile< Phosphine-free pincer-ruthenium catalyzed biofuel production: high rates, yields and turnovers of solventless alcohol alkylation>, COA of Formula: C8H9FO, the main research area is phosphine pincer ruthenium biofuel solventless alc alkylation.
Phosphine-free pincer-ruthenium carbonyl complexes based on bis(imino)pyridine and 2,6-bis(benzimidazole-2-yl) pyridine ligands have been synthesized. For the β-alkylation of 1-Ph ethanol with benzyl alc. at 140 °C under solvent-free conditions, (Cy2NNN)RuCl2(CO) (0.00025 mol%) in combination with NaOH (2.5 mol%) was highly efficient (ca. 93% yield, 372 000 TON at 12 000 TO h-1). These are the highest reported values hitherto for a ruthenium based catalyst. The β-alkylation of various alc. combinations was accomplished with ease which culminated to give 380 000 TON at 19 000 TO h-1 for the β-alkylation of 1-Ph ethanol with 3-methoxy benzyl alc. DFT studies were complementary to mechanistic studies and indicate the β-hydride elimination step involving the extrusion of acetophenone to be the overall RDS. While the hydrogenation step is favored for the formation of α-alkylated ketone, the alcoholysis step is preferred for the formation of β-alkylated alc. The studies were extended for the upgradation of ethanol to biofuels. Kinetic studies indicate first order dependence on concentration of both the catalyst and ethanol. Phosphine-free catalytic systems operating with unprecedented activity at a very low base loading to couple lower alcs. to higher alcs. of fuel and pharmaceutical importance are the salient features of this report.
