Reactivity
Diphenylketene can undergo attack from a host of nucleophiles, including alcohols, amines, and enolates with fairly slow rates. These rates can be increased in the presence of catalysts. At present the mechanism of attack is unknown, but work is underway to determine the exact mechanism.
Synthesis
Diphenylketene is produced by the elimination of hydrogen chloride from diphenylacetyl chloride in the presence of triethylamine.
