Attempted hydroformylation of triacetyl-D-glucal Cameron, Christina Janet

Abstract

Triacetyl-D-glucal, an unsaturated sugar has been prepared and submitted to the hydroformylation reaction, which is the addition of carbon monoxide and hydrogen to an unsaturated compound at high pressure and temperature. A cobalt catalyst is generally used, in this case, cobalt acetate tetrahydrate. The mixture of products obtained was separated by column chromatography and distillation. The main products are probably triacetyl-D-deoxyglucose obtained by the addition of water to the starting material, 1,2-hydroglucal obtained by hydrogenation of the starting material, a small amount of the theoretical hydroformylation compound and varying amounts of the starting material.
