Te2(CF3)2 kristallisiert in der monoklinen Raumgruppe P21/a mit vier Formeleinheiten in der Elementarzelle. Die Gitterkonstanten betragen a = 10,13(1) Å, b = 11,489(7) Å, c = 6,822(8) Å und β = 101,20(8)°. Bei der Umsetzung von Te2(CF3)2 mit der äquimolaren Menge Iod entsteht CF3TeI in quantitativer Ausbeute, eine Isolierung gelingt nicht. Die NMR‐Spektren zeigen eine starke Lösungsmittelabhängigkeit. Durch Metathesereaktionen werden die Verbindungen CF3TeX (X = CCC6H5, t‐C4H9, SCN, SC6F5) synthetisiert.
High oxidation state transition metal fluorides are selective fluorinating agents for dichloromethane; those with do electronic configurations undergo hydrogen-fluorine exchange and metal reduction, while dn species undergo chlorine-fluorine exchange.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
