Rhodium-Catalyzed Dehydrogenative Germylation of C–H Bonds: New Entry to Unsymmetrically Functionalized 9-Germafluorenes
摘要:
Rhodium-catalyzed dehydrogenative germylation leading to unsymmetrically functionalized 9-germafluorenes via GeH and CH bond activation is described. Despite the significant achievements made in dehydrogenative functionalization of CH bonds, only a limited number of examples with the fourth-row atomH bonds have been reported. The current method enabled the synthesis of various 9-germafluorene derivatives, including tetracyclic as well as donoracceptor substituted germoles, which may be useful for electronic device applications.
