Preparation of 3-acetylbenzofuran-2(3H)-ones and 3-acetylnaphthofuran-2(3H)-ones via intramolecular rhodium carbenoid insertion
Abstract
Rhodium(II) acetate catalysed decomposition of aryl 2-diazobutyrates and naphthyl 2-diazobutyrates results in the formation of 3-acetylbenzofuran-2(3H)-ones and 3-acetylnaphthofuran-2(3H)-ones respectively.
