Role of aldehyde dehydrogenase in hypoxic vasodilator effects of nitrite in rats and humans [PDF]

, 2015
Hypoxic conditions favour the reduction of nitrite to nitric oxide (NO) to elicit vasodilatation, but the mechanism(s) responsible for bioconversion remains ill defined.

Reductive cleavage of N,N′-di-tert-butylcarbodiimide generates tert-butylcyanamide ligands, (Me3CNCN)−, that bind potassium both end-on and side-on in the same single crystal

Acta Crystallographica Section E: Crystallographic Communications, 2020
N,N′-Di-tert-butylcarbodiimide, Me3CN=C=NCMe3, undergoes reductive cleavage in the presence of the GdII complex, [K(18-crown-6)2][GdII(NR2)3] (R = SiMe3), to form a new type of ligand, the tert-butylcyanamide anion, (Me3CNCN)−.
