Reduction of diimino compounds to diamino compounds |
摘要 |
Organic diamines can be prepared by hydrogenating a preformed diimine in the presence of methanol and in the further presence of the tertiary alkyl mono-amine used to make the diimino compound. The diamino compounds thus obtained are useful as catalysts in the preparation of polyphenylene oxide resins.
