when using [Cu(dmp)(xantphos)]PF6 as the PC (62% vs. 11% reported by Minozzi et al., Table ), likely a result in part of the different reaction setups. Primarily, the photon flux of the light sources used (390 nm Kessil PR160L vs purple LED flexible strips, for the two setups, respectively) vary considerably and are probably the main culprit for the discrepancy in yield.
