Abstract

La(GaMe4)3 and (C5Me5)La(GaMe4)2 are obtained by reacting La(AlMe4)3 and (C5Me5)La(AlMe4)2, respectively, with GaMe3·OEt2. Diethyl ether as a donor reverses the commonly observed Ln–GaR4→ Ln–AlR4 transformation by producing the more stable AlMe3·OEt2, thus making homoleptic and half-sandwich tetramethylgallate complexes of the largest rare-earth metal accessible.
