Imido osmium(VIII) complexes are versatile oxidants for C−C double bond functionalisation. Despite their structural similarity with OsO4 their reactivity cannot always be compared with this seminal reagent. Detailed investigations including kinetic competition experiments are presented that uncover the electronic and steric preferences of osmium imido complexes. The different behaviour of OsO4 and
亚氨基锇 (VIII) 配合物是用于 C-C 双键功能化的多功能氧化剂。尽管它们与 OsO4 的结构相似,但它们的反应性并不总是与这种开创性试剂相比。详细的研究包括动力学竞争实验,揭示了锇酰亚胺配合物的电子和空间偏好。阐明了 OsO4 及其亚胺衍生物对叔胺和二胺的不同行为。Hammett 相关性研究表明,各个氧化剂的反应谱范围从 OsO4 的强亲电行为到 OsO(NtBu)3 遇到的相当亲核的特征。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
