photoinitiators (PIs) for radical polymerization of acrylates show only poor photoreactivity because of the undesired effect of back electron transfer. To overcome this limitation, PIs consisting of a benzaldoxime ester and various sensitizers based on aromatic ketones were introduced. The core of the photoinduced reactivity was established by laser flash photolysis, photo-CIDNP, and EPR experiments at short
由于背电子转移的不良影响,用于丙烯酸酯自由基聚合的典型双分子光引发剂 (PI) 仅显示出较差的光反应性。为了克服这一限制,引入了由苯甲醛肟酯和各种基于芳香酮的敏化剂组成的 PI。光致反应的核心是通过激光闪光光解、光 CIDNP 和短时间尺度的 EPR 实验建立的。根据这些结果,最初形成的亚胺基不是特别活跃。聚合主要由以 C 为中心的自由基引发。Photo-DSC 实验显示的反应性可与经典的单分子 I 型 PI 相媲美,如 Darocur 1173。
A facile zinc-mediatedBarbier-typeallylation of aromatic aldoxime esters, producing the corresponding protected homoallylic hydroxylamines, which are readily converted into homoallylic hydroxamic acids, is described.

An indium mediated procedure has been developed for the allylation of activated O-functionalised oximes and nitriles as exemplified by a variety of glyoxylate derivatives. This method gives the corresponding free (or protected) amine in a one pot-process. The method is regiospecific and is carried out under remarkably mild conditions so that even oxime esters can be subjected to the typical reaction conditions.
