We present the insertion behavior of the alkyl-substituted germylene Ge(Flu) in different E-X σ bonds (E = Au, Si, Ge, Sn), first with the isolation of the germylgold complex (Flu)Ge(Cl)AuPPh. Afterward, the oxidative addition of GeCl to Ge(Flu) gives the digermane (Flu)Ge(Cl)GeCl, followed by a reductive elimination of GeCl and the formation of the oxidation product (Flu)GeCl. A comparable behavior is observed, with the homologues ECl (E = Si, Sn) stopping at different steps of the reaction.

Catalysis using low-valent main-group compounds is usually done under inert conditions; no example of such catalysis has been doable entirely in ambient conditions until now. This aspect is addressed in this work through an air- and water-stable germylene cation [DPMGe][(OH)B(CF)] (2) (DPM=dipyrromethene); it efficiently catalyzes aldehyde and ketone hydrosilylations under ambient conditions. Detailed theoretical studies reveal that compound 2's stability is bolstered by the interaction between the anion and germanium's frontier orbitals.

Introducing phospha-bicyclohexene (BCH)-germylenes (BCHGe's) as a novel, multifunctional compound class: the title compounds 15-18 are obtained from simple salt metathesis reactions of dipotassium germacyclopentadienediides K[1] with phosphorusdichlorides. The BCHGe's 15-18 are stabilized by homoconjugation of the germanium(ii) centre with the remote C[double bond, length as m-dash]C double bond. Despite substantial thermodynamic stabilization, phospha-BCHGe's are reactive and undergo a reductive elimination of elemental germanium to give the corresponding phospholes.

The aminotroponiminate (ATI) ligand stabilized germylene cation [(i-Bu)ATIGe][B(CF)] (2) is found to be an efficient low-valent main-group catalyst for the cyanosilylation of aldehydes and ketones (ATI=aminotroponiminate). It was synthesized by reacting [(i-Bu)ATIGeCl] (1) with Na[B(CF)]. The catalytic cyanosilylation of diverse aliphatic and aromatic carbonyl compounds (aldehydes and ketones) using 0.
