The combination of two synergistic mechanisms leading to enhanced product yields is unusual in photoredox catalysis. Although much research has been devoted to dual catalysis, this involves the combination of a PC with an additional catalyst, such as a transition metal catalyst or hydrogen atom transfer catalyst. In this form of dual catalysis, both catalysts are typically required in order for the target product to be formed, while in our study we demonstrate that both pDTCz-DPmS and HE work independently of one another, contributing synergistically to the product yield.
