Novel 1-(3-benzofuranyl)-2-phcnylethanones 4a-d have been prepared by acetylation of 2-alkylbenzo-furans 2a-c with phenylacetyl chlorides 3a-b. The methoxy derivatives 4b-d have been demethylated to the corresponding phenols 5b-d with pyridinium hydrochloride. An attempt to obtain the derivatives of 4d and 5a iodinated in the phenyl ring has been undertaken. The novel compounds have been characterized
