A cuprous chelate bearing a secondary sphere hydrogen bonding functionality, [(PV-tmpa)Cu I ] + , transforms • NO (g) to N 2 O (g) in high-yields in methanol. Ligand derived proton transfer facilitates N-O bond cleavage of a putative hyponitrite intermediate releasing N 2 O (g) , underscoring the crucial balance between H-bonding capabilities and acidities in (bio)chemical • NO (g) coupling systems.
