The novel ortho-metallated complex (R,R)-di-µ-chlorobis9-[(1-dimethylamino)ethyl]-10-phenanthrenyl-C,N}dipalladium has been prepared and found to be a significantly better catalyst than its phenyl and naphthylamine analogues for the asymmetric Claisen rearrangement of a non-activated allyl imidate.
制备了新型正交金属化复合物 (R,R)-二-µ-氯双9-[(1-二甲基氨基)乙基]-10-菲-C,N}二钯,并发现在非活化烯丙基亚胺的不对称克莱森重排反应中,该复合物是一种明显优于其苯基和萘胺类似物的催化剂。
