adenosine derivatives with tributyl- or triphenylgermane hydride (AIBN/toluene/Δ) effected radical-mediated germyldesulfonylations to give 5′-(tributyl- or triphenylgermyl)methylene-5′-deoxyuridine and adenosine derivatives as single (E)-isomers. Analogous treatment of 2′-deoxy-2′-[(phenylsulfonyl)methylene]uridine with Ph3GeH afforded the corresponding vinyl triphenylgermane product. Stereoselective halodegermylation
