sodium methoxide in methanol; no rearrangement (ring-expansion) is observed. They react with anthracene to give 9-chloro- and 9,10-dichloro-anthracene and with anisole to give chloroanisole (mainly the para-isomer). Triphenylarsine reacts with the NN-dichloroamide to give (after reductive work-up) an arsoranylideneamine, which can also be prepared from the amide (5) and diacetoxytriphenylarsorane.
1-氨基2,2,3,4,4-pentamethylphosphetan 1-氧化物(5)和二叔丁基次膦酰胺(9)可以被转化成Ñ -monochloro-和NN二氯衍生物用叔丁基或次氯酸钠。所述Ñ -monochloroamides在溶液中的部分不相称。它们可以通过从含有等摩尔量的适当酰胺和NN-二氯酰胺的溶液中蒸发溶剂而方便地制备。该ñ -monochloroand NN(5)的-二氯衍生物在甲醇中被甲醇钠还原成酰胺。没有观察到重排(环扩展)。它们与蒽反应生成9-氯-和9,10-二氯蒽,并与苯甲醚生成氯苯甲醚(主要是对-异构体)。与三苯基胂发生反应NN -dichloroamide,得到(后还原进行后处理)的arsoranylideneamine,其也可以从酰胺(5)和diacetoxytriphenylarsorane制备。
