A metal-free method for the N-arylation of amidines and N,N-disubstituted amidines using o-silylaryl triflate under very mild reaction conditions is developed. The reactions are compatible with a variety of functional groups. Imines can also be N-arylated by this method. Preparation of substituted phenanthridines via a Pd catalyzed intramolecular cyclization of the iodine containing N-arylation product
开发了一种无金属的方法,可在非常温和的反应条件下,使用三氟甲磺酸邻甲硅烷基芳基酯对am和N,N-二取代am进行N-芳基化。反应与各种官能团相容。亚胺也可以通过这种方法被N-芳基化。证明了通过Pd催化含碘的N-芳基化产物的分子内环化反应制备取代的菲啶。
