摘要：

The synthesis and comprehensive characterization of a series of base-stabilized ChX(2) (Ch=Se, Te, X = Cl, Br) Is reported using aryl-substituted diazabutadiene and 2,2'-bipyridine (bipy) its the ligands In stark contrast to free ChX(2) the complexes display excellent thermal stability Their use as viable ChX(2) reagents that relay be stored for later use is demonstrated in principle. The syntheses are simple. and high-yielding froth commercially available or easily synthesized reagents. The bipy complexes arc exceedingly rare examples of this ubiquitous ligand being utilized within Group 16 chemistry. the Se examples arc the first to be characterized by X-ray crystallography, and the To species are only the second
