Abstract

The heteroaromatic compounds with N-atoms in their molecular structure can produce a significant impact on the kinetics of oxidative transformation as directed by chromium(VI). These compounds are well-recognized as ‘promoters’ on account of their rate enhancement property in chromium(VI) oxidation kinetics. As revealed from the literature, the electron transfer step becomes facile when the N-containing heteroaromatic compounds are susceptible to shape the conjugates proficiently with chromium(VI) species during redox processes. Noticeably, the suitable orientation of binding sites of heteroaromatic compounds produces faster oxidation kinetics. The present review comprehensively highlights the specific role of N-heteroaromatic compounds in chromium(VI) oxidation along with the crucial factors responsible for influencing the rate of redox transformation. The utility and scope of such compounds in the field of analytical chemistry are also emphasized in this account.

n -杂芳香族化合物对铬（VI）定向氧化有机基质的影响

分子结构中含有n原子的杂芳香族化合物会对氧化转化动力学产生显著影响。这些化合物被公认为“促进剂”，因为它们在铬（VI）氧化动力学中的速率增强特性。从文献中可以看出，当含n杂芳香化合物在氧化还原过程中容易与铬（VI）形成共轭物时，电子转移步骤变得容易。值得注意的是，杂芳香族化合物结合位点的合适取向产生更快的氧化动力学。本文综述了n -杂芳香族化合物在铬（VI）氧化中的特殊作用以及影响氧化还原转化速率的关键因素。这类化合物在分析化学领域的用途和范围也被强调。图形抽象
