D. Witthaut et al., Isolation of a catenated organotelluride anion in the sodium borohydride reduction of diphenylditelluride, ORGANOMETAL, 19(24), 2000, pp. 5238-5240
Far more complex than anticipated is the widely utilized reductive cleavage
of diorganoditellurides with sodium borohydride. The isolation and charact
erization of [Pn(C6H5)(4)][TeC6H5)(3)] (Pn = P, As) suggests that diphenyld
itelluride is reactive toward the hydride as well as to the phenyltellurola
te anion.
