  Competing oxygen migrations inortho nitro aromatic thioamides on electron impact

  摘要：

  AbstractInteresting competitive oxygen migrations from the nitro group to the nitrogen and to the sulfur have been noticed during the mass spectral decomposition of ortho nitro aromatic thioamides on electron impact. The migration of the oxygen to the nitrogen of the thioamide function results in the formation of stable o‐nitrosothiobenzoyl cation. The other novel ortho effect noticed in the ortho isomers is the transfer of an oxygen from the nitro group to the sulfur followed by the ejection of SO from the molecular ions. A mechanism involving the initial oxygen migration to the sulfur through a favourable 6‐membered transition state followed by cyclization with the concomitant expulsion of SO is proposed for this process. Other interesting decomposition processes occurring as a consequence of this ortho effect have also been noticed. The proposed mechanisms for these processes are supported by mass analysed ion kinetic energy spectra and high voltage scans.

  A solvent-free cross-coupling method for oxidative amidation of aldehydes and alcohols via a metal-free radial pathway has been demonstrated. The proposed methodology uses the TBAI-TBHP combination which efficiently induces metal-free C–H activation of aldehydes under neat conditions at 50 °C or ball-milling conditions at room temperature.

The 1H-NMR spectra show a preferential interaction of the anions with the urea group in receptors 1 and 2 due to the less steric hindrance, while there is a cooperative interaction of amide group in receptors 3 and 4 due to the closeness of both

  摘要 合成了一组新的基于脲基苯甲酰胺的受体 (1-4)；已经研究了它的结合亲和力和在溶液中与不同阴离子形成超分子复合物的能力。为了设计这些受体，考虑了尿素和酰胺基团（邻位和间位）以及发色团基团萘基和硝基苯基的位置的组合，产生四个受体。位置和发色团结构以 4>3>2>1 的顺序影响尿素和酰胺氢的酸度。所有光谱研究表明，在乙腈中存在不同 TBAX 盐的情况下，1 和 2 与 3 和 4 相比发生了显着变化。1H-NMR 谱表明，由于空间位阻较小，阴离子与受体 1 和 2 中的脲基团优先相互作用，
