Novel valence expansion reactions using KC_8: a new route to hexavalent organotellurium compounds from divalent tellurium

摘要

Hexavalent tellurium compounds, Ar_5(CH_3)Te, Ar_4(CH_3)_2Te, and Ar_2(CH_3)_4Te (Ar = 4-CF_3C_6H_4, Ph, 4-CH_3C_6H_4), were synthesized by the reaction of Ar_(2-n)(CH_3)_nTe (n=0-1) or Ar_(3-m)(CH_3)_mTe~+X~- (m=0-2) with KC_8 followed by the treatment with CH_3I.
