Implication

Experimental analysis reveals differences in small molecule reactivity among plutonium, uranium, and samarium complexes, indicating transuranic elements' significance.

Abstract

(NHPh)] (4-U). The difference in reactivity of 1-Pu compared to complexes 1-Sm and 1-U was unexpected, and since SIR chemistry can enable complexes to participate in otherwise impossible reductive transformation of substrates, this reinforces the importance of studying small molecule reactivity with the transuranic elements.
