temperatures. A mechanistic scheme implying initial amine exchange between 1 and the added amine leading to the N,N-dimethyl analog 5 is suggested. An improvedsynthesis where the reactive intermediate 5 is formed in situ from triphenylphosphine, carbon tetrachloride and HNR3R4 is described.
相反,早期观察,Ñ甲基Ñ -phenylaminotriphenylphosphonium碘化1(的Murahashi试剂)不与醇和伯或仲胺反应在温和的条件(80℃)下,得到仲胺或叔胺。但是,该反应可以在较高的温度下成功进行。提出了一种机械方案,该方案暗示1与添加的胺之间的初始胺交换,从而导致N,N-二甲基类似物5。改进的合成方法,其中反应性中间体5由三苯基膦,四氯化碳和HNR 3 R 4原位形成 描述。

The preparation and 1H NMR spectra of some di-μ-chloro-bis(N,N-dialkylbenzylamine-2,C,N)dipalladium(II) complexes, and the corresponding monomeric triphenylphosphine derivatives are described. A reaction sequence is presented for the cyclopalladation reaction and some improved conditions for the preparation of these complexes are presented.
描述了一些二微米氯双(N,N-二烷基苄胺-2,C,N)二钯(II)配合物的制备及1 H NMR光谱,以及相应的单体三苯基膦衍生物。给出了环钯反应的反应顺序,并给出了制备这些配合物的一些改进条件。
