This compound can be activated by reacting it with trifluoroacetic anhydride, but a stronger and more common activator of this compound is oxalyl chloride.
This compound can be reacted with acetic anhydride in a step passing through an ylide intermediate in the Pummerer rearrangement. A solution of phosphorous pentoxide containing this molecule catalyzes a polymerization reaction between carbohydrates. Like betaine, this compound is used to enhance the yield and specificity of (*) PCR. This compound can be activated by reacting it with trifluoroacetic anhydride, but a stronger and more common activator of this compound is oxalyl chloride. The intermediate resulting from that reaction is used to oxidize primary or secondary alcohols under mild conditions without the use of chromium. For 10 points, name this polar aprotic solvent used in the Swern Oxidation and containing a central sulfur atom.
