Synthetic Radical Reactions Using Dibutylchlorogermane and ­Dibutylethoxygermane as Radical Mediators

Abstract

In the presence of Et₃B as radical initiator, dibutylchlorogermane (1a) and dibutylethoxygermane (1b) reacted with bromo- and iodoalkanes at room temperature to give the corresponding alkanes in high yields. Hydrogermane 1a was more reactive than 1b. However, 1b worked as a better radical mediator in intermolecular radical addition of haloalkanes to electron-deficient alkenes.

9a The preparation of 1a was carried out by the following steps: butylation of GeCl₄ with BuMgBr, dealkylative dichlorination of Bu₄Ge with AlCl₃ and AcCl, reduction of Bu₂GeCl₂ with LiAlH₄, and chlorination of Bu₂GeH₂ with CuCl₂.

The use of Bu₂SnH₂ as reducing agent was also attempted for the reduction of 2a. The Et₃B-initiated reaction with Bu₂SnH₂ (1.2 equiv) for 24 h gave 3a in 34% yield with recovery of 2a (ca. 50%).
