Benzophenone dichloride

The benzophenone dichloride was prepared by heating equivalent molecular quantities of benzophenone and phosphorus pentachloride to 145-150° for two hours and then fractionating the mixture under reduced pressure. The product used for this preparation boiled at 201-202°/35 mm. [Pg.95]

Larger runs using roo g. of benzophenone dichloride gave the same percentage yields of product. [Pg.95]

Thiobenzophenone has been prepared by the action of thio-phosgene on benzene in the presence of aluminum chloride 1 by the action of phosphorus pentasulfide on benzophenone 2 by the action of alcoholic potassium sulfide on benzophenone dichloride 3 by treating benzophenone dichloride with an alcoholic solution of sodium hydrosulfide 4 and by the action of thioacetic acid on benzophenone dichloride.5... [Pg.95]

The halogen atoms of the geminal dihalo derivatives of diaryl diketones and of heterocyclic ketones can be replaced in reactions with sulfur compounds 0e.g., sodium hydrogen sulfide, thioacetic acid, phosphorus pentasulfide), thioketones being formed.318,319 Staudinger and Freudenberger,320 for instance, obtained thiobenzophenone in 46% yield from benzophenone dichloride (dichlorophenylmethane) and a hot alcoholic solution of sodium hydrogen sulfide ... [Pg.640]
