Abstract

The coordination of low‐valent group 13 organyls E^I^R [E = Al, Ga, In; R = Cp*, C(SiMe~3~)~3~] to transition metals has attracted increasing interest over the past decade. Complexes and cluster compounds of these new ligands with a number of transition metals have been isolated and characterised. The E^I^R moiety is formally isolobal with CO and PR~3~ (R = alkyl, Cp*) or carbenes (R = chelating group) with varying σ‐donor and π‐acceptor properties depending on the organic group R as well as the group 13 metal E. In this review, different ways of forming M−E bonds such as substitution reactions of labile ligands or insertion of E^I^R into transition metal halide bonds are described. Furthermore, the reactivity of homoleptic complexes M~a~(E^I^R)~b~ is discussed, outlining the use of these new complex types in bond activation reactions. (© Wiley‐VCH Verlag GmbH & Co.
