Description

Tert-butylhydrazine ((CH3)3CN2H3) is a potential reductant with exceptional selectivity for the reduction of Np(VI), yet the reduction mechanism of Np(VI) with (CH3)3CN2H3 remains unclear. Herein, we explored the reduction reaction of Np(VI) with (CH3)3CN2H3 using scalar-relativistic density functional theory. We found that the first Np(VI) reduction in pathway I and the second Np(VI) reduction in pathway III is kinetically optimal among three pathways I–III. The reduction nature of Np(VI) is revealed by the bond distance of Np-Oyl and spin density of Np. This work theoretically expands the understanding of Np(VI) reduction with hydrazine derivatives.
