✦ Synopsis

The potassium ion intercalated in graphite results in unique reactivity of Ar Te K C (1), formed by cleavage of one of the Te-C(Ar) bonds of Ar Te by KC . Thus, 1 reacted quantitatively with CH I to give Ar TeCH , which was not obtainable from Ar Te Li . The Te-CH bond of Ar TeCH is cleaved in preference to the Te-C(Ar) bonds, and formation of Ar Te(CD ) suggests the intermediacy of the hypervalent dianion Ar Te .
