“…In 1980, Cardaci and Ossicini reported the successful enantioseparation of chiral anions of the type [M(ox) 3 ] 3− [M = Co(III) or Cr(III)] (where ox is oxalate) using solutions of brucine, cinchonine, and quinine acetates as electrolytes under high-voltage paper electrophoresis conditions [25]. In early 1980s, Fanali et al used extensively high-voltage paper electrophoresis and high-performance paper electrophoresis [26], allowing good separation within few minutes, to study the enantioseparation of chiral metal ions like [Co(en 3+ , and [Co(en)(dip) 2 ] 3+ with either antimonyl potassium (+)-tartrate, arsenic sodium (+) tartrate, or (-)-disodium tartrate/AlCl 3 as electrolytes [27,28].…”

Over time, chiral organometallic compounds have attracted great interest in several fields, with applications going across several disciplines of chemical, biological, medical, and material sciences. In the last decades, due to advancements in molecular design and computational modeling, the chemistry of chiral transition metal complexes had a remarkable flowering, with the development of new structures for applications in asymmetric synthesis, bioinorganic chemistry, and molecular recognition. In these fields, fast chiral analysis to determine the enantiomeric purity of organometallic structures prepared by asymmetric synthesis, and for high‐throughput screening of analytes, catalysts, and reactions, is very important. Capillary electrophoresis and related techniques proved to be extremely versatile for chiral analysis, showing unsurpassed advantages compared to chromatography like low consumption of materials, production of limited amounts of waste, fast equilibration, and possibility to replace easily type and concentration of the chiral selector, among others. Furthermore, electromigration techniques may be useful to gain details about the stereochemistry of the enantiomers of new compounds and to study analyte–selector noncovalent interactions at molecular level. On this basis, this short review aims to provide the reader with a comprehensive view on the enantioseparation of organometallic compounds by electromigration techniques, examining the topic from the historical perspective and showing what was made in this field so far, an essential know‐how for developing new and advanced applications in the next future.

“…Due to its chemical properties, the modified CD is negatively charged at any commonly used pH in CE. These features allow its use in a charged form over a wide pH range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Recently this CD has been used successfully for enantiomeric separations of several positively and negatively charged compounds of pharmaceutical interest.…”

Capillary electrophoresis is a powerful tool for chiral separation of ionogenic enantiomers in solutions. This article brings an overview of the theory of electrophoretic separations with special emphasis on enantiomer-chiral selector equilibria, followed by a survey of indirect separations, based on formation of diastereomers with different electrophoretic mobilities, and a comprehensive appraisal of direct separations when the chiral recognition stems from (i) host-guest interactions using cyclodextrins and crown ethers as hosting agents, (ii) ligand exchange mechanism, (iii) affinity interactions or (iv) a combination of solute-chiral selector interactions with micellar electrophoretic transport. Finally, some trends in chiral separations by capillary electrophoresis are discussed.
