摘要：
The reaction of pentaphenyltellurium chloride 2 with silver perchlorate afforded the pentaphenyltelluronium salt, Ph5Te+ClO4-, (1b), and treatment of 2 with silver triflate and sodium tetakis(3,5-bis(trifluoromethyl)phenyl/borate provided Ph5Te+ [3,5-(CF3)(2)C6H3](4)B- (1c), which were isolated as stable yellow solids. X-ray crystallographic analyses of the hypervalent telluronium salts revealed square-pyramidal geometry around the tellurium, which ave ave examples for penta-substituted main group element compounds.
