Triorganogermanium hydrides

Bowman [6] has reported the synthesis of new, solid-phase triorganoger-manium hydrides 28 and 29 by addition of triorganogermanium hydride unit 27 to Merrifield and Quadragel resins (Scheme 6).

Triorganogermanium hydride resins 28 and 29 were then evaluated in a range of radical transformations [6]. For example, treatment of thioim-idazolide 30 with 28 gave the deoxygenated product 31 in moderate yield (Scheme 7), while quadragel-derived hydride resin 29 was used to mediate the radical cycUzations of amide 32 and ether 34 to give lactam 33 and tetrahy-drobenzofuran 35 respectively in good yield (Scheme 7).
