“…Readily available coordination compounds of rare-earths and early transition metals such as Sc(OTf) 3 , NbCl 5 , , YCl 3 , ZrCl 4 , , have been employed as popular catalyst for various transformations due to their high Lewis acidity . In reactions that are strictly related to the cycloaddition of CO 2 to epoxides, coordination compounds of yttrium and scandium have been reported as efficient catalysts for cycloadditions reactions of various dipolarophiles to epoxides. , Indeed, rare earth metal complexes are highly active Lewis acids for the cycloaddition of CO 2 to epoxides under mild conditions. − …”

Cyclic organic carbonates represent a relevant class of chemicals that can be prepared from CO 2 by cycloaddition to epoxides. The application of efficient catalysts is crucial in allowing the cycloaddition reaction to proceed under very mild conditions of temperature, pressure, and CO 2 concentration, thus resulting in a sustainable and carbonbalanced approach to CO 2 conversion. This is particularly the case if impure waste CO 2 could be employed as a feedstock. In this Review, we have critically analyzed the burgeoning literature on the cycloaddition of CO 2 to epoxides with the aim to provide state-of-the-art knowledge on the catalysts that can convert CO 2 to carbonates under ambient conditions. These have been systematically organized in families of compounds and critically scrutinized in terms of catalytic activity, availability and mechanistic features. Finally, we provide an overview on the catalytic systems able to function using diluted and impure CO 2 as a feedstock.

“…However, the predominant use of zirconium in chemistry is in the application of organometallic catalysis including olefin metathesis[39], ring-opening polymerizations[40], aminoalkene hydroamination[41], and other reactions. [42-44] For different catalytic and waste separation purposes, a number of different zirconium coordination complexes have been studied, however, in the context of the construction of 89 Zr-labeled bioconjugates for PET, only a handful of stable, aqueous, bio-compatible complexes are appropriate.…”

The advent of antibody-based cancer therapeutics has led to the concomitant rise in the development of companion diagnostics for these therapies, particularly nuclear imaging agents. A number of radioisotopes have been employed for antibody-based PET and SPECT imaging, notably 64Cu, 124I, 111In, and 99mTc; in recent years, however, the field has increasingly focused on 89Zr, a radiometal with near ideal physical and chemical properties for immunoPET imaging. In the review at hand, we seek to provide a comprehensive portrait of the current state of 89Zr radiochemical and imaging research, including work into the production and purification of the isotope, the synthesis of new chelators, the development of new bioconjugation strategies, the creation of novel 89Zr-based agents for preclinical imaging studies, and the translation of 89Zr-labeled radiopharmaceuticals to the clinic. Particular attention will also be dedicated to emerging trends in the field, 89Zr-based imaging applications using vectors other than antibodies, the comparative advantages and limitations of 89Zr-based imaging compared to that with other isotopes, and areas that would benefit from more extensive investigation. At bottom, it is hoped that this review will provide both the experienced investigator and new scientist with a full and critical overview of this exciting and fast-developing field.

“…Zirconium can also be a part of high entropy alloys, known for their structural and phase formation features (Yurchenko et al, 2017;Zhao et al, 2017). Zirconium compounds (oxide, alloys, and salts) are widely used as catalysts, for example in redox reactions and isomerization reactions (Zhang & Li, 2009;Molnar, 2011;Vining, Strunk & Bell, 2011;Cao et al, 2016;Keitl et al, 2017); in the perfumery industry, they are used as components of antiperspirants (Shen and Nardello-Rataj 2009).…”

Abstract Detailed monographs on the analytical chemistry of zirconium, which is widely used in all fields of modern science and technology, were published in the 1960s–1970s of the last century. This review summarizes information on the modern methods for determination of zirconium in a great variety of natural, technical, and biological objects. Focus is made on the works published in scientific periodicals after 2005. Spectroscopic techniques of zirconium determination including molecular and atomic spectrometry, X-ray fluorescence analysis, and electrochemical and activation methods are described. The paper also describes the applications of zirconium compounds, in particular, in analytical chemistry.
