Chemistry and reactivity

Diphenylketene can undergo nucleophilic attack from a host of nucleophiles, including alcohols, amines, and enolates with fairly slow rates. These rates can be increased in the presence of various catalysts. At present the mechanism of attack is unknown, but various work is underway to determine the exact mechanism.
