ChemInform Abstract
The title compounds (III) are prepared from (I) and trichloroethene (II) by a well known one-step procedure. The title compounds (III) which are stable, are not isolated, but treated in situ with furan (IVa) or 2-methylfuran (IVb) to give the hitherto unknown compounds (V), which result from C-amidoalkylation reactions. The reactions between the title compound (IIIa) and 2-hydroxymethylfuran (VI)or furan-2-carboxylic acid (VIII) yield the novel compounds (VII) or (IX), which are the products of O-arenesulfonamido alkylation. The title compounds do not react with furans carrying electronegative substituents, as e.g. 2-acetylfuran or 2-ethoxyfuran.
