Synthesis and Diverse Transformations of a Dinitrogen Dititanium Hydride Complex Bearing Rigid Acridane‐Based PNP‐Pincer Ligands

Abstract

Studies on N 2 activation and transformation by transition metal hydride complexes are of particular interest and importance.T he synthesis and diverse transformations of ad initrogen dititanium hydride complex bearing the rigid acridane-based acri PNP-pincer ligands {[( acri PNP)Ti] 2 (m 2 -h 1 :h 2 -N 2 )(m 2 -H) 2 }a re presented. This complex enabled N 2 cleavage and hydrogenation even without additional H 2 or other reducing agents.F urthermore,d iverse transformations of the N 2 unit with av ariety of organometallic compounds such as ZnMe 2 ,M gMe 2 ,A lMe 3 ,B (C 6 F 5 ) 3 ,P inBH, and PhSiH 3 have been well established at the rigid acri PNP-ligated dititanium framework, such as reversible bonding-mode change between the end-on and side-on/end-on fashions,d iborylative N = N bond cleavage,the formal insertion of two dimethylaluminum species into the N = Nb ond, and the formal insertion of two silylene units into the N=Nbond. This work has revealed many unprecedented aspects of dinitrogen reaction chemistry.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
