Boron-Catalyzed Site-Selective Reduction of Carbohydrate Derivatives with Catecholborane
Catalytic sp3 C–O bond cleavage using B(C6F5)3/HBcat is reported. This method is first demonstrated on simple ethers and silyl protected alcohols, which exhibit reactivity parallel to the knownExpand

Positional Selectivity in the Hydrosilylative Partial Deoxygenation of Disaccharides by Boron Catalysts
The catalytic partial deoxygenation of the per-silylated gluco-disaccharides maltose, cellobiose, trehalose, and isomaltose by Me2EtSiH and the Lewis acid catalyst B(C6F5)3 have been examined toExpand

Controlling Sugar Deoxygenation Products from Biomass by Choice of Fluoroarylborane Catalyst
The feedstocks from biomass are defined and limited by nature, but through the choice of catalyst, one may change the deoxygenation outcome. We report divergent but selective deoxygenation of sugarsExpand
