Catalytic Activation of N(2)O at a Low-Valent Bismuth Redox Platform

[Image: see text] Herein we present the catalytic activation of N(2)O at a Bi(I)⇄Bi(III) redox platform. The activation of such a kinetically inert molecule was achieved by the use of bismuthinidene catalysts, aided by HBpin as reducing agent. The protocol features remarkably mild conditions (25 °C,...

description [Image: see text] Herein we present the catalytic activation of N(2)O at a Bi(I)⇄Bi(III) redox platform. The activation of such a kinetically inert molecule was achieved by the use of bismuthinidene catalysts, aided by HBpin as reducing agent. The protocol features remarkably mild conditions (25 °C, 1 bar N(2)O), together with high turnover numbers (TON, up to 6700) and turnover frequencies (TOF). Analysis of the elementary steps enabled structural characterization of catalytically relevant intermediates after O-insertion, namely a rare arylbismuth oxo dimer and a unique monomeric arylbismuth hydroxide. This protocol represents a distinctive example of a main-group redox cycling for the catalytic activation of N(2)O.
