An Improved One-Pot Method for the Preparation of 2-Substituted 1H-Perimidines
摘要:
2-substituted H-1-perimidines are readily prepared, in high yields, by refluxing a mixture of sodium pyrosulfite, an aldehyde, and 1,8-diaminonaphthalene in aqueous ethanol or N,N-dimethylformamide. The method is of wide applicability except from araldehydes bearing a strong electron-withdrawing group (-CN, -NO2).

The present invention provides perimidine-based carbene compounds that exhibit high electron donating activity. These compounds are particularly useful as ligands to form transition metal complexes. Such complexes may be catalytically active for a wide range of desirable chemical reactions for organic synthesis.
