Recent developments in the non-cyclopentadienyl organometallic and related chemistry of scandium

Abstract

Up to the early to mid 1990s the organometallic chemistry of scandium was dominated by cyclopentadienyl derivatives. This present article highlights advances in the synthesis and reactivity of non-cyclopentadienyl organometallic and related compounds of scandium. These include: compounds containing arene and other η^x-C_xR_x ligands; compounds with macrocyclic and fac-L₃ ligands; compounds with polydentate ligands that incorporate amide donors; compounds with bidentate, monoanionic N,N′ donor ligands; and compounds with iminophenolate, bis(phenoxide) and some other anionic O-donor ligands.
