selective synthesis of primary aminesfrom easily available precursors is attractive yet challenging. Herein, we report the rapid synthesis of primary aminesfrom alkenes via metal‐free regioselective hydroamination at room temperature. Ammonium carbonate was used as ammonia surrogate for the first time, allowing for efficient conversion of terminal and internal alkenes into linear, α‐branched, and α‐tertiary

plug-and-play, continuous-flow chemical synthesis system that mitigates this challenge with an integrated combination of hardware, software, and analytics. The system software controls the user-selected reagents and unit operations (reactors and separators), processes reaction analytics (high-performance liquid chromatography, mass spectrometry, vibrational spectroscopy), and conducts automated optimizations
自优化反应器 化学家花费大量时间调整已知反应的条件。温度和浓度的微小变化会对产品产量产生很大影响。贝达德等人。提出一个基于流的反应平台,可以自动执行这项艰巨的任务。通过使用来自集成分析的反馈,系统会收敛到最佳条件,然后可以高精度地应用这些条件。一系列具有加热、冷却、混合和光化学功能的模块可以配置用于广泛的反应。这些包括均相和非均相钯催化的交叉偶联、还原胺化以及在惰性气氛下生成敏感中间体。科学,这个问题 p。1220 基于流动的模块化系统使用实时反馈来优化有机化学中广泛使用的反应条件。化学合成通常需要劳动密集型的、有时是乏味的、反复试验的反应条件优化。在这里,我们描述了一种即插即用、连续流动的化学合成系统,它通过硬件、软件和分析的集成组合来缓解这一挑战。系统软件控制用户选择的试剂和单元操作(反应器和分离器),处理反应分析(高效液相色谱、质谱、振动光谱),并进行自动优化。该系统的能力在 CC 和

The functionalization of unactivatedC(sp3)-H bonds poses a significant challenge due to their ubiquity and relative similarity in most organic frameworks. Herein, we describe the use of a combined photoredox and nickel catalytic system for the regioselective C(sp3)-C(sp3) coupling of unactivatedC(sp3)-H bonds and alkyl bromides. Positional selectivity is dictated by a 1,5-hydrogen atom transfer (HAT)
