Organometallic Reagents for Synthetic Purposes: Tellurium

Abstract

As principais aplicações sintéticas de reagentes contendo telúrio foram reunidas e estão apresentadas a seguir.An overview of the most important applications of tellurium compounds in Organic Synthesis is presented.

Isolation of Tellurite- and Selenite-Resistant Bacteria from Hydrothermal Vents of the Juan de Fuca Ridge in the Pacific Ocean

“…The impressive number of publications on Te compounds during the last few years shows that Te is now widely used in applied chemical reactions (37). The natural Te cycle, however, has not been investigated, and the role of microbes in this process has not yet been elucidated.…”

Synthesis and Characterization of Methyl(perfluoroalkyl)Tellurium(II) Compounds, MeTeRf (Rf = CF3, C2F5), the Corresponding Tellurium(IV) Dihalides, MeTe(Rf)X2 (X = F, Cl, Br, I), and Bis(trifluoroacetates), MeTe(Rf)(OCOCF3)2

“…Our research work on perfluoroorgano tellurium compounds in different oxidation states1 allowed us during the last decades to give new insights into the manifold chemistry and structural diversity of perfluoroorgano tellurium compounds. Organotellurium derivatives in general have attracted significant attention for the conversion of functional moieties in many fields of organic synthesis 2. Together with the knowledge that the TeCF 3 moiety resembles iodine theoretically3 and experimentally,4,5 we assumed these investigations to be helpful for a better understanding of tellurium chemistry in general.…”

Photopolymerization of n-Butyl Methacrylate in Solutions Initiated by Diphenyl Ditelluride

“…A search of the literature reveals that applications of diphenyl ditelluride (DPDT) in the field of organic chemistry and biology have been well documented [14,15]. However, its applications in the field of polymer science are of recent origin * To whom correspondence should be addressed.…”
