Diphenylketene is used for acylation of carboxylic acids to give mixed anhydrides; cycloaddition with a variety of unsaturated
compounds; synthetic source of diphenylallenes.
synthetische
Preparative Methods of Diphenylketene: originally prepared by zinc reduction of α-chlorodiphenylacetyl chloride; oxidation
of benzil monohydrazone with yellow Mercury(II) Oxide followed by thermal rearrangement of the α-diazo
ketone; dehydrohalogenation of diphenylacetyl chloride with Triethylamine; debromination of α-
bromodiphenylacetyl bromide by the action of Triphenylphosphine.
