The complex, prepared via comproportionation and transmetalation, reacted with N 2 O at ambient temperature within 1 min, producing alcohol and N 2 . This contrasts sharply with slower reactions of (bpy)NiEt 2 (12 h) and catalytic systems (22 h). Theoretical studies suggest a stepwise organometallic Baeyer–Villiger mechanism via a Ni(II)–oxyl intermediate. The high reactivity of Ni(I)–alkyl challenges the notion of N 2 O’s inertness, highlighting its potential as a versatile oxidant in synthesis.
