Dehydrogenative Double C−H Bond Activation in a Germylene‐Rhodium Complex
Transition metal tetrylene complexes offer great opportunities for molecular cooperation due to the ambiphilic character of the group 14 element. Here we focus on the coordination of germylene [(Ar(Mes2))(2)Ge :] (Ar(Mes)=C(6)H(3)‐2,6‐(C(6)H(2)‐2,4,6‐Me(3))(2)) to [RhCl(COD)](2) (COD=1,5‐cyclooctadi...

description | Transition metal tetrylene complexes offer great opportunities for molecular cooperation due to the ambiphilic character of the group 14 element. Here we focus on the coordination of germylene [(Ar(Mes2))(2)Ge :] (Ar(Mes)=C(6)H(3)‐2,6‐(C(6)H(2)‐2,4,6‐Me(3))(2)) to [RhCl(COD)](2) (COD=1,5‐cyclooctadiene), which yields a neutral germyl complex in which the rhodium center exhibits both η (6)‐ and η (2)‐coordination to two mesityl rings in an unusual pincer‐type structure. Chloride abstraction from this species triggers a singular dehydrogenative double C−H bond activation across the Ge/Rh motif. We have isolated and fully characterized three rhodium‐germyl species associated to three C−H cleavage events along this process. The reaction mechanism has been further investigated by computational means, supporting the key cooperative action of rhodium and germanium centers. |
