There are two mechanisms we have to write out. alpha-D-glucose is the starting material for both of them and the solvent for both of them is acetic anhydride. The first mechanism includes sodium acetate to yield beta-penta-acetate and the first mechanism includes zinc chloride (Lewis acid) to form an oxonium ion to yield the alpha-penta-acetate product. Any help to draw out the mechs would be much appreciated
Method for Trapping a Gas, The decomposition of 3-sulfolene to form 1,3-butadiene generates 1 mole of sulfur dioxide gas per mole of 1,3-butadiene. Substantial quantities of SO2 would be generated if this decomposition were carried out on a large ..
