Hydrogenolysis of isosorbide to diols and triols over a heterogeneous SiO2-supported Rh catalyst†
Abstract
Silica-supported Rh (Rh/SiO2) was an effective and reusable heterogeneous catalyst for the hydrogenolysis of isosorbide, providing diols and triols in 58% total yield. The yield was higher than those obtained by hydrogenolysis of glucose and sorbitol, confirming the high potential of isosorbide as a biomass-derived intermediate for the synthesis of polyols.
