“…In general terms, chalcogen interactions find very practical applications in a range of contexts beyond biology and medicine [16] , [17] , [18] , such as in molecular/anion recognition [19] , [20] , [21] , [22] , catalysts [23] , [24] and materials science [25] , [26] . With this level of activity, it is not surprising there are several authoritative reviews of chalcogen bonding [27] , [28] , [29] , [30] , including reviews of different physiochemical procedures for their detection in phases other than in crystals [31] , [32] , [33] , the primary importance of X-ray crystallographic investigations notwithstanding.…”

Selenium‐NMR Spectroscopy in Organic Synthesis: From Structural Characterization Toward New Investigations

et al. 2020

View full text Add to dashboard Cite

This review article deals with organic synthesis from the perspective of selenium-77 nuclear magnetic resonance (NMR) spectroscopy. Different types of organic reactions are briefly discussed, incorporating mechanism aspects through 77 Se NMR observable intermediates and byproducts. The 77 Se NMR experiments are demonstrated in terms of structural characterization and new insights for organic reactions. The ability to visualize different molecules in a reaction mixture provides a facile and versatile route for the development of synthetic organoselenium compounds. Thus, the review describes the strategies accomplished mainly in the past five years in the syntheses and applications of the organoselenium compounds, focusing on 77 Se NMR spectroscopy.

An evaluation of the Cambridge Structural Database for crystals containing Se … N secondary--bonding interactions was conducted. The presence of Se … N secondary-bonding interactions has been established in nearly 9% of crystals of mono-nuclear selenium compounds where such interactions can potentially form, that is, having at least one nitrogen atom. The Se … N interactions feature in 71 zero-dimensional, usually di-nuclear aggregates, 63 one-dimensional chains and tapes, and smaller numbers of two-and three-dimensional arrays, that is seven and one, respectively. Selenium(II) compounds form the majority of the dataset with only eight selenium(IV) compounds included in the survey. In most cases (112 out of 142), the selenium centre forms a single Se … N contact with 26 aggregates having a selenium atom forming two contacts and four examples where three Se … N contacts are evident. The great propensity of selenadiazole rings (75%) and selenocyanates (50%) to form Se … N secondary-bonding interactions in their crystals is particularly noteworthy.
