Boragermene 3 featuring a double bond between the Ge and dicoordinate B atoms has been synthesized for the first time by reacting the cyclic (alkyl)(boryl)germylene–PMe 3 adduct 1 with Cl 2 BN(SiMe 3 ) 2 followed by reductive dehalogenation with KC 8 . Addition of a Lewis base ( Me NHC) to 3 leads to the formation of the corresponding adduct 4 , which shows double bond character between the Ge and tricoordinate B atoms. Compound 3 undergoes hydrogenation with H 2 concomitant with a complete scission of the Ge=B bond.
