Abstract
A novel family of organochalcogens, Ph5TeX (X = Cl, Br), was readily obtain ed by the halogenation of Ph5TeLi, which was prepared by reaction of 5 equi v of PhLi with 1 equiv of TeCl4 or TeBr4; Ph5TeF was obtained by treating t he bromide with KF. The Te atom is in the highest oxidation state, Te(VI), and is covalently bonded to the halogen atom, in contrast to the ionic bond ing in (R3TeX)-X-IV.
