The structure of the 1,3-diphenyl-2-azaallyl anion–potassium ion pair and its oxidative coupling by zirconium(IV)
Abstract
Deprotonation of PhCHN–CH2Ph by KH in tetrahydrofuran in the presence of 18-crown-6 led to the isolation of the 2-azaallyl anion–potassium ion pair [PhCH
N
CHPh]⋯[K(18-crown-6)] which was oxidatively coupled to a diimino ligand by Cp2ZrCl2 to form [Cp2Zr(η2-PhCH–N–CH(Ph)CH(Ph)–N
CHPh-η1)].
