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 [PhCHNCHPh]⋯[K(18-crown-6)] which was oxidatively coupled to a diimino ligand by Cp₂ZrCl₂ to form [Cp₂Zr(η²-PhCH–N–CH(Ph)CH(Ph)–NCHPh-η¹)].
