In chemistry, the term pseudo-oxocarbon anion is used to refer to a negative ion that is conceptually derived from an oxocarbon anion through replacement of one or more of the basic oxygen atoms by chemically similar elements or functional groups, such as sulfur (S), selenium (Se), or (=C(CN)2). Typical examples are the anions 2-(Dicyanomethylene)croconate, croconate violet, and croconate blue, derived from the croconate anion C5O2−5 by replacing one, two, or three oxygen atoms by dicyanomethylene groups: These anions retain many of the properties of the parent, including the delocalized bond in the ring and the delocalized charge in the atoms attached to the ring. Similar anions can be obtained from squarate C4O2−4. (Wikipedia).

Aspirin to Acetaminophen - Part 6 of 6: Acetaminophen from p-aminophenol
This is the final part of the series, where the p-aminophenol is converted to the acetaminophen. Using acetic anhydride, the p-aminophenol is going to be acetylated. The reaction is carried out in water at room temperature. Acetic anhydride does react with water, but it happens slowly.
