Reductive trapping of dinitrogen by molybdenum tris anilide to form a dinitrogen anion and chemistries thereof

Abstract

The isolation and characterization of the anoinic dinitrogen complex, [Na][N_2Mo(N[t-Bu]Ar)_3] (Ar=3,5 dimethylaryl) has been accomplished. The capture of dinitrogen also occurs during the formation of (RR'N)_3TiN_2Mo(N[t-Bu]Ar)_3 where R=t-Bu and R'=Ph or R=R'=Me. Activation of small molecules with these dinitrogen complexes has been studied encompassing an array of CS_2 and CO_2 reactions. Elimination of dinitrogen from the anionic complex formed the η^2 complex, (Ar[t-Bu]N)_3Mo(CS_2SiMe_3).
