title: Rhodium-catalyzed dehydrogenative germylation of C-H bonds: new entry to unsymmetrically functionalized 9-germafluorenes.
abstract: Rhodium-catalyzed dehydrogenative germylation leading to unsymmetrically functionalized 9-germafluorenes via Ge-H and C-H bond activation is described. Despite the significant achievements made in dehydrogenative functionalization of C-H bonds, only a limited number of examples with the fourth-row atom-H bonds have been reported. The current method enabled the synthesis of various 9-germafluorene derivatives, including tetracyclic as well as donor-acceptor substituted germoles, which may be useful for electronic device applications.
