Abstract

We report ammonia oxidation by homolytic cleavage of all three H atoms from a [Mo-NH3]+ complex using the 2,4,6-tri-tert-butylphenoxyl radical to yield a Mo-alkylimido ([MoNR]+) complex (R = 2,4,6-tri-tert-butylcyclohexa-2,5-dien-1-one). Chemical reduction of [MoNR]+ generates a terminal MoN nitride complex upon N-C bond cleavage, and a [MoNH]+ complex is formed by protonation of the nitride. Computational analysis describes the energetic profile for the stepwise removal of three H atoms from [Mo-NH3]+ and formation of [MoNR]+
