摘要 |
<p>Preparation of 1,3- or 1,4-phenylene-bis-oxazolidines (I) by reacting a dicyanobenzene (II) with a 2-aminoalkanol (III) in presence of catalyst in which a mixture of catalyst, (III) and optionally solvent is treated at reaction temperature with (II). 1,3- or 1,4-phenylene-bis-oxazolidines of formula (I) are prepared by reacting a dicyanobenzene of formula (II) with a 2-aminoalkanol of formula NH 2-CR 1R 2-CR 3R 4-OH (III) in presence of catalyst. A mixture of catalyst, (III) and an optional solvent is treated at reaction temperature with (II): [Image] R 1to R 4hydrogen or 1-3C alkyl An independent claim is included for preparation of (I) by reacting (II) and (III) is presence of zinc 2-ethylhexanoate as catalyst.</p> |
