  Catalytic activities of Mn(I) complexes derived from expensive MnBr(CO)₅ salt have been explored in various dehydrogenative transformations. However, the reactivity and selectivity of inexpensive high spin Mn(II) complexes are uncommon. Herein, we have synthesized four new Mn(II) complexes and explored switchable alkenylation and alkylation of methyl heteroarenes employing a single Mn(II)catalyst. The developed protocol selectively furnishes a series of functionalized E‐heteroarenes and C‐alkylated heteroarenes with good to excellent yields. Various medicinally and synthetically useful compounds are successfully synthesized using our developed protocol. Various controls and kinetics experiments were executed to shed light on the mechaism,which reveals that α‐C−H bond breaking of alcohol is the slowest step.

  摘要 从昂贵的锰溴(CO)5 盐中提取的锰(I)配合物在各种脱氢转化中的催化活性已得到探索。然而，价格低廉的高自旋锰（II）配合物的反应活性和选择性并不常见。在此，我们合成了四种新的 Mn(II) 复合物，并利用单一 Mn(II) 催化剂探索了甲基杂环戊烯的可切换烯化和烷基化。所开发的方案可选择性地获得一系列官能化的 E- 异烯烃和 C- 烷基化的异烯烃，且收率良好甚至极佳。利用我们开发的方案成功合成了各种药用和合成有用的化合物。我们进行了各种控制和动力学实验来揭示其机理，结果表明，醇的α-C-H 键断裂是最慢的一步。
• Synthesis and Photophysical Investigation of a Series of Push–Pull Arylvinyldiazine Chromophores

  A new series of push-pull arylvinyldiazines has been efficiently prepared by aldol condensation between the appropriate methyldiazine and aromatic aldehyde. The optical absorption and emission properties of these chromophores were studied in different solvents and media. These compounds act as polarity sensors with a strong positive emission solvatochromism. This behavior suggests a highly polar emitting state, which is characteristic of compounds that undergo an internal charge transfer upon excitation. These molecules also exhibit halochromic properties and are potential colorimetric and luminescence pH sensors. The second-order nonlinear properties have been investigated for some of the compounds, and large and positive mu beta are obtained, in particular, for pyrimidine derivatives.
