Cyclicimides were selectively reduced to the corresponding ω‐hydroxylactams in high yields with (EtO)3SiH (triethoxysilane) or PMHS (polymethylhydrosiloxane) under catalysis of zinc diacetate dehydrate [Zn(OAc)2⋅2 H2O] (10%) and tetramethylethylenediamine (TMEDA) (10%). This catalytic protocol showed good functional group tolerance as well as excellent regioselectivity for unsymmetrical imides bearing

symmetry and provide evidence that the central Mo atoms are linked by a single bond and coordinated by two isoindole nitrogen atoms and two nitrogen atoms from the amine moieties. The electronic absorption bands extend into the 1200-1500 nm region. This can be explained using Gouterman's four-orbital theory. The experimental NMR data and theoretical calculations provide evidence for a heteroaromatic
在尿素存在下,使用正常的 Pc 形成条件合成了具有两个 Mo 或 W 中心金属离子和四个异吲哚环部分的扩展酞菁 (Pc) 同系物。产品已通过电化学表征;质谱(MS);红外、电子顺磁共振 (EPR)、核磁共振、电子吸收和磁圆二色 (MCD) 光谱;和 X 射线分析。X 射线结构具有矩形 C(2v) 对称性,并提供证据表明中心 Mo 原子通过单键连接并由两个异吲哚氮原子和来自胺部分的两个氮原子协调。电子吸收带延伸到 1200-1500 nm 区域。这可以使用 Gouterman 的四轨道理论来解释。
