摘要:由于修饰的模块性质和当与金属离子配位时观测到的反应性范围,因此钳子分子越来越受到关注.钳分子家族中的一个子集使用吡啶基桥接两个外部臂,并为金属结合提供一个n供体原子.尽管对臂部附件进行了广泛的研究,但对中央取代的吡啶系统的电子效应进行的研究很少.因此,合成了一系列nnn钳型配体,它们在吡啶环的4位上被-Oh,-Obn,-H,-Cl和-No2官能团取代,并通过NMR光谱和esi-Hrms进行表征.每个钳子都用cu(II)盐金属化,并通过x射线衍射分析,循环伏安法和密度泛函理论分析进行评估.结果表明,相对未被研究的-Obn基团同时具有吸电子(xrd键长)和给电子(NMR光谱)特性.与其他研究的同类物相比,-No2钳形配体在评估的实验窗口内显示出氧化还原事件.此外,基于dft研究和循环伏安法,给电子基团增加了cu(II)中心附近的电子密度.在考虑配体设计时,这些发现可应用于其他基于吡啶的钳系统,

摘要:α,β-Unsaturated aldehydes are useful products as such in agrochemistry, but also potential intermediates for the preparation of important insect pheromones and kairomones. Until now, primarily the thermodynamically more stable (E)-α,β-unsaturated aldehydes have been identified as useful intermediates in the production of conjugated diene pheromone compounds, however, their practical and cost-effective synthesis on an industrial scale remains challenging. The problem to be solved by the present invention is to provide a method for selective oxidation of alkenes to α,β-unsaturated carbonyls which can be further transformed into pheromones and kairomones preferably without isolation and significant loss of the existing stereochemical purity.

摘要:A control circuit of a power converter is provided. The control circuit comprises a PWM circuit, a sample circuit, and emulation circuit. The PWM circuit generates a switching signal for switching an inductor and generating a switching current of the inductor in response to a current feedback signal. The sample circuit is coupled to sample a switching current signal into a capacitor during an on time of the switching signal. The emulation circuit generates a discharge current couple to discharge the capacitor during an off time of the switching signal for generating the current feedback signal. The switching current signal is correlated to the switching current of the inductor, and the discharge current is generated in response to an input voltage of the inductor, an output voltage of the power converter, and the on time of the switching signal.
