Impact of N-heteroaromatic compounds in chromium(VI) directed oxidation of organic substrates

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.
