A one-step synthesis of diaryl and alkyl-aryl ketones by the reaction of car☐ylic acid with Grignard reagents in the presence of NiCl2(Ph2PCH2CH2PPh2) as catalyst is described. In the nickel-catalyzedGrignardreaction the formation of alcohols is nearly completely suppressed.

The reaction between bromine and 1,1-diphenylalkan-1-ols is shown to proceed by dehydration to an alkene, followed in aqueous acetic acid by formation of a bromohydrin which may then rearrange to a ketone. A number of new bromohydrins and bromoalkenes have been prepared.
