“…Nitration of NOM using 15 N-labeled reagents could be of use as a molecular tagging method for structure elucidation, as it is complementary to hydroxyl modifying methods, but greater control over the specificity of the reaction by using alternative reagents would be desirable. A recent review by Liu lists alternatives that could be tried …”

Natural organic matter (NOM) is the product of microbial and abiotic decay of plant and animal remains in terrestrial and aquatic ecosystems. On a molecular level, NOM is a complex mixture of organic molecules, of which the vast majority of structures are unknown. By identifying these molecules, our understanding of the many functions of NOM could be greatly enhanced. However, given that they are chromatographically inseparable and number in the thousands, traditional analytical techniques have proven unable to achieve this goal. A promising approach to enumerate functional groups and elucidate molecular structures within NOM is based on a combination of molecular tagging and high resolution spectroscopic techniques, such as nuclear magnetic resonance spectroscopy and mass spectrometry. Molecular tagging involves the selective modification of particular functional groups, inserting nuclei to act as reporters on their surrounding chemical environment. This allows examination of only the tagged molecules within NOM, thereby reducing the complexity of the mixture. In this review, the effectiveness of molecular tagging methods incorporating carbon, silicon, nitrogen, phosphorus, and deuterium into NOM are discussed. Some potential tagging methods which have not yet been applied to NOM are also presented.

“…Inorganic reagents, such as nitric acid, 24 nitrogen oxides (N x O y ), 25 nitronium 26 and nitrosonium salts, 27 as well as metal nitrates and nitrites 28 are already well-established with numerous publications highlighting their properties. 29 However, progress in the field of organic nitrating reagents has not been addressed to date, despite their 120 years history. Thus, given that the development of organic nitrating reagents is a rapidly growing field that opens new horizons in nitration chemistry, herein, we provide a summary and analysis of this research topic to late 2021.…”

Nitro compounds are vital raw chemicals that are widely used in academic laboratories and industries for the preparation of various drugs, agrochemicals, and materials. Thus, nitrating reactions are of great importance for chemists and are even taught in schools as one of the fundamental transformations in organic synthesis. Since the discovery of the first nitrating reactions in the 19th century, progress in this field has been constant. Yet, for many years the classical electrophilic nitration approach using a mixture of strong mineral acids dominated the field. However, in recent decades, the attention of researchers has focused on new reactivity and new reagents that can provide access to nitro compounds in a practical and straightforward way under mild reaction conditions. Organic nitrating reagents have played a special role in this field since they have enhanced reactivity. They also allow nitration to be carried out in an ecofriendly and sustainable manner. This review examines the development and application of organic nitrating reagents.1 Introduction2 Organic Nitrating Reagents2.1 Alkyl Nitrites2.2 Nitroalkanes2.3 Alkyl Nitrates2.4 N-Nitroamides2.5 N-Nitropyrazole2.6 N-Nitropyridinium Salts3 Organic Nitrating Reagents Generated In Situ3.1 Acyl Nitrates3.2 Trimethylsilyl Nitrate3.3 Nitro Onium Salts4 Organic Nitronium Salts5 Organic Nitrates and Nitrites5.1 Ammonium Nitrates5.2 Heteroarylium Nitrates5.3 Other Organic Nitrates5.4 Organic Nitrites6 Conclusion and Outlook
