摘要：

Te for two: Supported by pyridine- or carbene-based ligands, tellurium-centered dications are prepared in high yield and include a dicationic tellurium analogue of the recently synthesized "carbodicarbene". The key to accessing these compounds is the isolation of a base-stabilized form of TeOTf2 (see structure), a new highly electrophilic reagent for tellurium chemistry. © 2009 Wiley-VCH Verlag GmbH & Co.
