| Abstract: | Stable unsaturated heterocycles such as benzofuran are difficult to remove from petroleum by conventional catalytic hydrotreating. However, in a model system, coordination of Mn(CO)3+ to the aromatic ring of benzofuran activates the C−O bond towards insertion of Pt(PPh3)2] Eq. (1)]. The insertion is preceded by precoordination to the furan C=C bond; thus, the 2,3-dihydro analogue of 1 , which lacks this double bond, does not undergo insertion of the Pt moiety. |
