摘要

The reaction of phosphorus pentachloride with cyclic fluorocarbon sulfonic acids leads first, with loss of hydrogen chloride, to a high melting solid, which decomposes upon strong heating to yield the sulfonic anhydride. The non-cyclic acids produce a mixture of anhydride and sulfonyl chloride. The higher-boiling sulfonic anhydrides are cleaved, above 200, by metal salts such as sodium fluoride, zinc chloride, and aluminum chloride. Sulfonyl ...
