N-烷氧基-O-烷基羟胺与银氧化物在乙醚中容易地反应，以几乎定量的产率得到N，N ′-二烷氧基-，'-二烷氧基肼。这些肼对强酸和强碱非常敏感，并且不经历正常类型的酯水解。对甲苯磺酸在乙醚和正丙醇中的分解产物为正碳离子和烷氧羰基正离子的形成提供了证据。报道了一种新型混合酸酐--甲氧羰基对甲苯磺酸盐。
N-Carbalkoxy-O-alkylhydroxylamines react readily with silver oxide indiethyl ether to give N, N'-dicarbalkoxy-,'-dialkoxyhydrazines in almost quantitative yields. These hydrazines are very sensitive towards strong acids and bases and do not undergo the normal type of ester hydrolysis. The products from the decom-position with p-toluenesulfonic acid in diethyl ether and 1-propanol provided evidence for the formation of carbonium ions and carbalkoxylium ions. A new type of mixed anhydride, carbomethoxy p-toluenesulfonate, is reported.
