Abstract
Spectroscopic investigations discovered that the in-situ generated phenylhydrazone anion was signifi-cantly bathochromically shifted to visible light region for photoactivation under irradiation.The photoex-cited phenylhydrazone anion was potential to reduce aryl iodides via single electron transfer process for the subsequent radical chain reaction.A redox-neutral photochemical carbonylation of aryl iodides was developed on basis of the special spectroscopic features of phenylhydrazone anion.This protocol pro-vided a convenient and efficient synthetic tool for accessing carbonylation products under redox neutral conditions without the need of transition-metals.
