Pd/Ni → Ge-F interactions supported by phosphine-chelation were found to trigger dual activation of Ge-F bonds under mild conditions. This makes fluoro germanes suitable partners for catalytic Ge-C cross-coupling and enables Germa-Suzuki reactions to be a

Complexes OsH(η5-C5H5)(C≡CPh)(EPh3)( PiPr3) [E = Si (1), Ge (2)] react with 2.0 equiv of HBF4·OEt2 to give [OsH(η5-C5H5)(≡C-CH2Ph)(P iPr3)]BF4 (3). Treatment of 3 with KOH affords OsH(η5-C5H5)(=C=CHPh)(PiPr3 ) (5) in equilibrium with the metalated species OsH(η5-C5H5)(o-C6H4CH =CH)(PiPr3) (7) ΔH° = -3.6 ± 0.2 kcal mol-1 and ΔS° = -10.8 ± 1.9 cal K-1 mol -1 for the formation of 7). The addition of P(OMe)3 to the solution of the isomeric mixture leads to Os(η5-C5H5){(E)-CH=CHPh}{P(OMe)3 }(PiPr3) (8), which reacts with HBF4·OEt2 to give [Os(η5-C5H5)(=CHCH2Ph){P(OMe) 3}(PiPr3)]BF4 (4).
