A (C5Me5)/enolamido lutetium dinitrogen complex promoted by deprotonation on the amidinate ligand

Abstract

Selective deprotonation of the amidinate ligand in lutetium dinitrogen complex [{Cp*{MeC(NⁱPr)₂}Lu}₂(μ²-η²:η²-N₂)][K(crypt)] (Cp* = (C₅Me₅)⁻, crypt = 2,2,2-cryptand) afforded the novel Cp*/enolamido lutetium dinitrogen complex [{Cp*{H₂CC(NⁱPr)₂}Lu}₂(μ²-η²:η²-N₂)K][K(crypt)]. Due to the skeleton tension, a further rearrangement was confirmed with the formation of [{Cp*K{H₂CC(NⁱPr)₂}Cp*Lu}₂(μ²-η²:η²-N₂)][K(crypt)]₂.
