Organophosphorus-Catalyzed Reductive Functionalization of Nitrocompounds via P(III)/P(V) Redox Couple
Published 2022“…With the utilization of geometric-distorted organophosphetanes as catalysts and hydrosilanes as terminal reductants, nitro compounds (nitroarenes, nitromethane and nitroalkanes) undergo reductive O-atom transfer reactions involving the conversion of P(III)/P(V)=O. With that, boronic acids were employed as coupling partners to intercept the nitrene reactivity of nitro compounds derived oxazaphosphorane intermediates for direct reductive C–N coupling. …”
