more forcing conditions, products of the further hydrolysis of 6 are obtained. Acetolysis in acetic acid gives the benzyl acetates derived from both N- and O-substituents. With potassium tert-butoxide, the major path is abstraction of an O-benzyl hydrogen followed by fragmentation to the aldehyde and the benzyldiazotate ion. Possible mechanisms for the formation of the products are discussed.
的N,O-二苄基-N- nitrosohydroxylamines(水解的主要产物3)是denitrosated父羟胺(6); 在更强的条件下,获得了进一步水解6的产物。在乙酸中的乙酸水解得到衍生自N-和O-取代基的乙酸苄酯。对于叔丁醇钾,主要途径是提取O-苄基氢,然后裂解成醛和苄二重氮根离子。讨论了形成产物的可能机制。
