Dual NHC/Photoredox Catalytic Synthesis of 1,4-Diketones Using an MR-TADF Photocatalyst (DiKTa)

20 October 2022, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

The use of the recently reported organic multi-resonant thermally activated delayed fluorescence (MR-TADF) photocatalyst DiKTa allows for the modular synthesis of 1,4-diketones under mild and metal-free conditions. The reaction proceeds via a three-component relay process in the presence of an N-heterocyclic carbene (NHC) organocatalyst.
